(1) According to David Perkins, when a liquid is evaporating it's just molecules that are escaping into the air as a gas. In order for the molecules to be able to escape certain energy is needed,the molecule determines the amount of energy that's gonna be used. As an example he used the juggling of a tennis ball compared to a bowling ball. He says that it's gonna be harder to juggle a bowling ball because it has a bigger mass compared to the tennis thus causing more energy needed in the bowling ball. One of the factors affecting evaporation would be the mass of the molecules in the liquid. Another factor would be how stuck the molecules are together, if the molecules are stuck together and have a strong connection, evaporation would be much …show more content…
Evaporation is a crucial step to help the water cycle since without evaporation there would be no rain and no rain means no plants and no plants means no oxygen, meaning no us. Another thing apart from heat that helps evaporation is air pressure. If the pressure is high it means that water won't evaporate as fast, since the pressure pushes the molecules down making it hard for them to escape.
(4) In this article named How Relative Humidity Affects Evaporation written by Atula Gupta we discuss how relative humidity affects evaporation. Relative humidity the amount of water vapor in volume of air divided by the amount of air in that volume is called humidity. Depending on the temperature,the higher it is, it can increase the rate of evaporation and the amount of water vapor in the air. At a given temperature, there is a maximum amount of water vapor that air can hold and when the maximum capacity is reached the process of condensation
This is my research report on my science project. My topic is What Clear liquid affects the rate of evaporation. I chose this topic because I wasn’t able to choose a project I wanted to do. So I looked through the list and saw this topic. Then suddenly I think back to a wet afternoon and very cold a few years ago. That morning I saw a puddle of water and when I came back it was half way drained down. So i thought back to that moment long ago which I still remember. And so not only I needed a project, I also was a little interested into this topic. I was also interested into rates of evaporation when I saw this question. The question i’d be answering is What clear liquid has a faster evaporation rate.
The release or agitation of the water would release the co2 causing the water to rise and evaporate.
Condensation is the opposite of Evaporation. It is when saturated air cools down below the dew point which causes them molecules to stick together and from clouds. When we see clouds they don’t all look the same. This goes back to when the temperature causes the amount of water to evaporate. So that’s why clouds are all different shapes and sizes.
Evaporation- when water evaporates in the form of water vapor by the heat of the
that can still evaporate water. The wet bulb temperature is lower than the air temperature,
What is the relative humidity when the air temperature is 75 degrees Fahrenheit and the Wet Bulb temperature is 65 degrees Fahrenheit?
Growing up, we all went through the water cycle lesson and we will never forget it. The reason being, we encounter the water cycle throughout our entire life and it will always effect our systems and more importantly our water system. As illustrated in the picture, our water cycle includes the processes of evaporation, condensation, precipitation, which then goes to many places. During evaporation, the sun is used as a main power to make this happen. The sun’s rays beat down onto the ground creating all of the moisture and water to fizzle into a gas state into the atmosphere and get stored away into the clouds. When it is stored into the clouds it is condensing. Condensation means that the gas is again forming itself back into its liquid state to get ready to return to Earth. The condensation then forms into precipitation. Precipitation comes in many different forms. You can see it as rain, snow, sleet, or hail making its way back to us. What happens to it then depends on the area. The water might end up as runoff, or become
The water cycle is essential to the water systems surrounding Michigan. Shown on the picture, the water cycle has several steps, but the main processes are evaporation, condensation, and precipitation. Evaporation occurs when the water heats up and changes into a gaseous state, dispersing into the atmosphere.
2A. Evaporation is related to the properties of matter because it is a liquid and a gas. We know this because there are three states of matter which are soild, liquid and gas since evaporation first starts as a liquid (water). Then it turns into gas (cloud).
What is the relative humidity when the air temperature is 75 degrees Fahrenheit and the Wet Bulb temperature is 65 degrees Fahrenheit?
Definition of rate of evaporation. How it changes as temperature changes. Therate of evaporationcan be defined as the number of water molecules that change phase from liquid to gas each second. The rate of evaporation is mainly set by the temperature of the liquid water.The higher the temperature of the liquid water, the faster the rate of evaporation. Definition of rate of condensation. How it changes as vapor pressure (a measure the amount of the gas water vapor above the liquid surface) changes. Therate of condensationcan be defined as the number of water vapor molecules that change phase from gas to liquid each second. The rate of condensation depends mainly on the vapor pressure in the space above the liquid surface. Thus, the higher the concentration of water vapor molecules above the liquid surface, the faster the rate of condensation. What is meant by saturation Why will a closed system like this always move toward saturation with respect to water vapor You may take saturation to mean the capacity or maximum amount of water vapor that will can exist in the air at a particular temperature. It is important to understand that saturation vapor pressure (or the maximum amount of water vapor that can be in the air) increases exponentially as temperature
The water cycle represents how water is exchanged and cycled through Earth’s land, oceans, and atmosphere (2010 pg.1). Evaporation, condensation, and precipitation are all three main factors within the water cycle. Evaporation occurs when a liquids surface changes to gas. For example, when water from rivers, oceans or lakes evaporate, it becomes water vapor. Condensation occurs when gas changes to a liquid. For example, clouds form when water vapor condescends. Precipitation is described as any liquid or solid water that falls to earth from above. A great and simple example would be rain, snow or hail (2010 pg.1). Within the water cycle, there are three states of water: solid, liquid and gas. Most of Earth’s freshwater is
The water cycle is an ongoing process where water is constantly being changed from a liquid to a gas and back to a liquid. The water that is on the ground is evaporate into a vapor into the sky. Once the vapor is in the sky it condense and forms clouds. The cloud collect as much water as they can until, the water becomes too heavy and release the water back unto the ground. Then the whole water cycle the starts all over again.
HYDROLOGIC CYCLE The hydrologic cycle is a constant movement of water above, on, and below the earth's surface. It is a cycle that replenishes ground water supplies. It begins as water vaporizes into the atmosphere from vegetation, soil, lakes, rivers, snowfields and oceans-a process called evapotranspiration. As the water vapor rises it condenses to form clouds that return water to the land through precipitation: rain, snow, or hail. Precipitation falls on the earth and either percolates into the soil or flows across the ground. Usually it does both. When precipitation percolates into the soil it is called infiltration when it flows across the ground it is called surface run off. The amount of precipitation that infiltrates, versus the
Water vapor. Out of all the gases, water vapor makes the largest contribution to the Earth’s GHE (EPA, 2015). Water vapor has an atmospheric lifetime (AL) (defined as “the approximate amount of time it would take for the anthropogenic increment to an atmospheric pollutant concentration to return to its natural level (assuming emissions cease) as a result of either being converted to another chemical compound or being taken out of the atmosphere via a sink” (EPA, 2013)) of approximately 10 days (EPA, 2015). It is unlike other GHG and unique in the fact that when it reaches high enough concentrations in the atmosphere, it has the ability to condense into H2O liquid and can rain out from the atmosphere back to the surface of the Earth (EPA, 2015). It also acts as a feedback mechanism to climate change (IPCC, 2007; EPA, 2015). This is mainly due to two reasons. The first being that the total amount of H2O vapor that is in the atmosphere at any given time is directly related to the Earth’s surface temperature (EPA, 2015). Secondly, the H2O vapor in the atmosphere can affect the formation of clouds which directly influence the GHE by cooling (reflecting heat from the Sun) or by warming (trapping heat in the atmosphere) the surface of the Earth (EPA, 2015). Essentially, any change in clouds such as type, location, water content, altitude, particle size or shape, and lifetimes can influence their effect on the cooling and warming of the Earth (IPCC, 2013). Therefore, any
