Heat and Temperature

The study of science is Physics. Physics means the natural science which involves the study of things made up atoms or matter, and along with related concepts such as energy and force. The experiment is Physics because we are using heat from the sun, and transferring the heat to the oven. So heat or thermal energy is the measure of the amount of energy that is contained in a material. Heat depends on how much of the material, which would be sunlight, you have: if you have twice the amount then normal of whatever you are testing, then you have to double the amount of heat you have. “Temperature is a measure of the ability of a substance, or more generally of any living or nonliving subject, to move the energy made of heat to another living or nonliving subject.” “But we need to remember that light slows down has it goes farther from the sun, and bends toward the normal and has a shorter wavelength when it enters a higher value medium (A substance that makes it possible for the energy to move to one location to another)”. “ Also a light wave is transverse (they can be polarized).”

8. Create a graph: Select the GRAPH tab. Set the mass slider to 0 kg, and click Record to plot a point on the graph. Plot a point for each possible mass to create a graph showing the relationship between pressure and volume.

Calorimetry is the science of measuring the change in heat absorbed or released during a chemical reaction. The change in heat can tell us if the reaction is either exothermic - it released or heat into surroundings, or endothermic - it absorbed heat from surroundings. The device used to measure calorimetry is a calorimeter. A calorimeter can range from very expensive lab ones to coffee styrofoam cups but they are all tightly sealed in order to prevent heat from escaping.

Heat: The amount of energy associated with the movement of atoms and molecules in matter.

605). Energy cannot be created or destroyed; it only changes form. There are several sources of heat. These sources are chemical, mechanical, electrical, and nuclear.

Kinetic energy is the energy an object possesses due to its motion. The difference between kinetic energy and potential energy is the kinetic energy is the energy of an object that is already in

Heat is a form of energy, sometimes called thermal energy, which can pass spontaneously from an object at a high temperature to an object at a lower temperature. If the two objects are in contact, they will, given sufficient time, both reach the same temperature. Heat always travels from hot to cold objects and two objects will reach an equilibrium temperature. Heat flow is commonly measured in a device called a calorimeter, an insulating container that minimizes heat exchange between its contents and the surrounding. Heat flow in a device called a calorimeter. In this experiment, we should find the heat capacity of the

Kinetic energy is the energy that a body possesses by virtue of being in motion.

The heat capacity per unit mass of a body, called specific heat capacity or more simply specific heat, is used to more directly compare the heat capacity of substances. Pure water has high specific heat capacity that is exactly 1 calorie per gram, whereas other common substances have much lower specific heats. The reason is because it takes more energy to increase the kinetic energy of hydrogen-bonded water molecules than it does for substances in which the dominant intermolecular interaction is the much weaker van der Waals force. As a result, water gains or loses much more heat than other common substances while undergoing an equal temperature change.

There are four basic components for thermal energy (heat): 1. All matter is made up of tiny particles called atoms. These can only be seen with special microscopes. 2. The atoms are always moving – they all have kinetic energy. 3. The particles have space between them. Different states of matter have different amounts of space. 4. Adding heat (energy) to matter makes the particles move more quickly. Since faster moving things have more kinetic energy, adding heat increases the energy of the particle. 5. Cooling it down decreases the amount of kinetic energy and slows the movement down.

Chemists refer to the energy stored in a substance as the heat content or enthalpy of the substance. The heat of reaction is determined by the difference in the enthalpy between the reactants and products.

Specific heat is that amount of energy it takes to change the temperature of a given substance or material by 1 degree celsius. To calculate specific heat you can use the formula q=mcΔt where q= heat added, m=mass, c=specific heat, ΔT= final temperature- initial temperature. Different materials have different specific heats because some bonds between atoms are stronger than others and need more energy to break them. How do you distinguish between endothermic and exothermic reactions and

Temperature is a degree of heat or cold that and be measured by using thermometers. It is also a measure of the speed of atoms and molecules movement. Temperature is measured in degrees on the fahrenheit and celsius scales. Fahrenheit is a scale of temperatures in which 32° represents the melting point of ice and 212° represents the boiling point of pure water. Celsius is a scale of temperature in which 0° represents the melting point of ice and 100° represents the boiling point of water. Kelvin is a thermodynamic temperature scale based upon the efficiencies of ideal heat engines.

Thermal energy, however, is not the same as heat. Heat is energy transferred between substances or systems due to a temperature difference between them. Therefore it is correct to say that a system contains thermal energy, but it is incorrect to say that it "contains" heat. This is because heat refers to energy that is transferred from one thing to another. The quantity of heat transferred by a substance is reliant on on the speed and number of atoms or molecules in motion. The faster the atoms or molecules move, the higher the temperature. The more atoms or molecules that are in motion, the greater the amount of heat they transfer.

Heat is a form of energy that is transferred between two substances at different temperatures. The flow of the energy is from the object of higher temperature to the object of lower temperature. The heat is measured in units of energy, usually calories or joules. Temperature on the other hand, is how cold or hot an object is. The temperature is the average kinetic energy per molecule of a substance. This is measured in degrees on the Celsius or Fahrenheit or in Kelvins.
