maintain its body temperature and metabolism is the process in which energy is transformed within an organism’s body to maintain life. CSUSM comparative animal physiology students contained mice (Mus musculus) and Madagascar hissing cockroaches (Gromphadorhina portentosa) in vacuum tight contains to measure O2 consumption which would then translate into the mass specific metabolic rate (MSMR). With the comparison between mice in room and cold temperatures‚ mice held in cold temperatures had a higher

a step by step process in calculating the heat of fusion for ice and to compare the differences between salt added to room temperature water and salt added to icy water. To calculate heat of fusion‚ one must understand heat of fusion. Heat of fusion is the amount of heat required to convert a mass of a solid at its melting point into a liquid without an increase in temperature. As difficult as this may sound‚ this experiment can be carried out with minimal equipment. The following equipment was needed

Propriétés thermiques des matériaux polymères 1-Résumé La température de transition vitreuse (Tg) est probablement la propriété thermique la plus importante des polymères. Elle permet de déterminer la plage de température d’utilisation d’un polymère. On constate en effet‚ une diminution importante du module d’élasticité aux environ de la Tg. La Tg est influencé par plusieurs facteurs. Une faible masse moléculaire‚ des chaînes de polymères plus rigide‚ la présence de gros groupement latéraux

The Effect of Temperature on the Rate of the Reaction Between Calcium Carbonate and 1.0 M Hydrochloric Acid Josue Montoya IB Chemistry SL Mr. Pham Due Date: 07 March 2013 Dates Experiment Was Conducted: 27‚ 28‚ 29 February 2013 INTRODUCTION Research Question: How does altering the temperature at which calcium carbonate and 1.0 M hydrochloric acid react‚ affect the rate of reaction? Aim: The purpose of the experiment is to demonstrate

of water placed under the same conditions. This is because water has a higher specific heat capacity (4.18 J/g°C) compared to sand’s specific heat capacity (0.29 J/g°C). The specific heat capacity is how much heat energy it takes to change the temperature of the material one degree. Since water has a higher specific heat capacity it will take more heat energy and a longer amount of time to heat and cool. Experiment: “See lab sheet.” The control group was air. The air was the control group because

An Experiment to Test the Effect of Temperature on the Rate of Photosynthesis in Green Algae Background Photosynthesis is an amazing process where plants are able to create their own food as well as oxygen using sunlight‚ carbon dioxide (co2)‚ and water. The part of the plant responsible for photosynthesis is the enzymes in the chlorophyll (structures that carry out photosynthesis located in leaves). Photosynthesis is the process of creating glucose. Water + Carbon Dioxide + Sunlight = Glucose

lab is to determine the freezing and melting temperature of water. Freezing temperature‚ the temperature at which a substance turns from a liquid to a solid‚ and melting temperature‚ the temperature at which a substance turns from a solid to a liquid. Hypothesis If the water is at a low temperature then it will freeze. If it is at a high temperature then it will melt.

the volume and absolute temperature of a certain quantity of a gas are directly proportional. Mathematically‚ this can be represented as: Temperature = Constant x Volume or Volume = Constant x Temperature or Volume/Temperature = Constant Substituting in variables‚ the formula is: V/T=K Because the formula is equal to a constant‚ it is possible to solve for a change in volume or temperature using a proportion. Charles’ Law explains the relationship between temperature and volume of a gas. Assuming

Approaches to Temperature Control Temperature control in an air conditioning system is achieved by passing the air through the cooling or heating coil‚ which may use any of the following approaches: 1. Vary the temperature of air supplied to the space while keeping the airflow rate constant. This is the basic constant volume‚ variable temperature approach. 2. Vary the airflow rate while keeping the temperature constant for air supplied to the space. This is
