Temperature

The instrument used to measure temperature is a thermometer. There are many types of thermometers; the most common consist of a closed, graduated glass tube in which a liquid expands or contracts as the temperature increases or decreases. Many different types of thermometers work by detecting changes in the volume or pressure of an enclosed gas or by registering thermoelectric changes in a conductor (such as a thermistor or thermocouple). Galen, a Greek scientist and doctor made the first attempt

How does body temperature affect the locomotion of reptiles? Reptiles are a group of vertebrates that live under various environments both aquatic and terrestrial ranged from the tropical desert to the Arctic Ocean. Common types of reptiles include snakes, lizards, salamanders, crocodiles and turtles. Reptiles are ectoderms that adjust their own body temperature according to the environmental temperature, and reptiles can survive in relatively extreme temperatures. It is interesting to study whether

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems, for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

understand how temperature affects enzyme activity, and it is apparent that changes in temperature do have an effect on the enzyme catalase. The results obtained in the experiment a give increased insight in the role of enzymes in the human body. The chicken liver is similar to the human liver, and it is clear that catalase works at an optimum temperature of 22°C. This is important because humans maintain a stable body temperature of 37 °C, and with the aid of enzymes this temperature provides enough

hydrochloric acids at different temperatures will be used to observe the effect of temperature in dissolving Alka Seltzer tablets. Four different temperatures as 25 degrees Celsius, 45 degrees Celsius, 65 degrees Celsius, and 85 degrees Celsius will be arranged before the experiment by using a heating pad. 25 degrees Celsius indicates the average room temperature and equal increases will be chosen to observe different responses of Alka seltzer to different temperatures. Hydrochloric acid is a strong

paper) During this experiment, there were five sections of a temperature-gradient tank that were all different temperature ranges; 2-7 degrees Celsius, 7-12 degrees Celsius, 12-17 degrees Celsius, 17-22 degrees Celsius, and 22-27 degrees Celsius. The fish who were originally removed from the same stock tank (22 degrees Celsius) were then placed in the temperature-gradient tank. The experiment’s purpose was to observe which temperature of water the fish prefered best and gravitated towards. After

Introduction The purpose of this experiment was to design a calorimeter that successfully converted the energy from the combustion of the chip into heat to increase the temperature of the water. By measuring the temperature in the water from the beginning to the end and converting it into joules to see how much energy the water captured, we were able to complete the experiment. Literature review Energy is a very important property, it can only be conserved. Energy can’t be created or destroyed

full blast. It was a frigid cold day, the coldest it’s ever been. The weather man called for the temperature to be -59 degrees. I walked outside and the air made me feel like I couldn’t move. It was that cold. Living in Alaska, you’re already going to endure cold temperatures. In the article, “How would you hand;e -59 degrees?”, author Dan Joling wrote about Cynthia Erikson and the coldest temperature she has to endure. Cynthia lives in the village of Tanana, Alaska, which ranked at the coldest place

My question is “Does the temperature of a substance effect it’s ph?.” I will be testing this by using ph indicator strips that change color when it comes in contact with an acid or a base and comparing it with a color chart. The substances I will be using are vinegar, orange juice , and lemon juice. These can all be found at a local grocery store. The ph paper and color chart can be found at Walmart. Besides my experiment there have been other experiments that have tested temperature’s

Ice is a very slippery solid form of water and salt usually used usually to melt the salt. The reason salt melts the ice is because salt lowers the temperature for freezing ice so as the salt covers the ice the freezing point of the ice gets lowered (Holt, Rinehart, And Winston 2004). What is the best salt for lowering the freezing temperature of ice. The independent variable is all the different salts we are using, the dependent variable is the time in minutes that it will take to melt the ice.
