purpose of this experiment was to determine the optimum temperature range for the activity of the enzyme lactase. Extreme temperatures can have a detrimental effect on enzymes; very hot temperatures can cause the denaturation in the enzyme‚ which is the loss of protein structure. This causes a change in the shape of the enzyme leading to its inability to perform its function. As previously stated‚ the alternate hypothesis read: the optimal temperature range for lactase activity is between 23 to 25 ℃.

of the gas condenses back to the liquid state. If the temperature inside the container is kept constant‚ then the equilibrium at some point will be reached. When the equilibrium is reached‚ the rate of condensation is equal to the rate of evaporation and the rate of vapor pressure will remain constant as long as the temperature in the sealed container does not change. The relationship between the vapor pressure of a liquid and temperature is described in the Clausius-Clayperon equation: lnP= ∆Hvap

Exercise 17 Problems - Part I: Answers 1. The temperature contrast between the equator and the Arctic region is greatest in the winter‚ because the Arctic region is furthest away from the Sun during that time. 2. (a) The one region of the world where the hypothetical isotherm pattern is actually observed is in the Southern Hemisphere‚ starting at approximately 30° S. (b) The hypothetical pattern is seen here‚ because the oceanic and atmospheric circulations in this region constantly run from

up faster than water because it has a lower specific heat. Water has a specific heat‚ which requires one calorie of energy to raise the temperature of one gram of water by one degree Celsius. Sand has a lower specific heat. It takes .19 calories per gram to raise the temperature of the sand by 1 degree Celsius. Sand requires fewer calories to raise its temperature one degree Celsius and that’s why it heats up faster than water. Experiment: See lab sheet. In this experiment there was no control

Morphology on Ectotherm body temperature Introduction: Endotherms are organisms that maintain a stable body temperature. The environment has little effect. Endotherms consume different resources to maintain a stable body temperature trough changes in their metabolism. Ectotherms are organisms that cannot maintain a stable body temperature on their own. Ectotherms depend on its environmental surroundings to stabilize its body temperature. Stabile body temperatures are very important for Ectotherms

Estimation of the Activation Energy for the Iodination of Acetone Through the Effect of Temperature on the Rate Constant Joel Costa‚ Alex Fuentes‚ Michael Chea‚ Rex Nwerem Dr. Morgan Ferguson July 9‚ 2013 ABSTRACT | It is often important to determine the rate at which a chemical reaction takes place‚ i.e.‚ how fast it yields the desired products. Temperature is one of the factors that influence the rate of reactions and it does so by providing energy to reactant particles so that a larger

The following simulations were carried out on Aluminum alloy A356 to determine the effect of initial temperature of the billet on the forging load. The simulations were carried out at different temperatures between the solidus and liquidus temperature range of the alloy. The position of the billet on the bottom die was determined by placing it in different positions and also for various temperatures. The present location was finalized after studying the aspect of under filling of die cavity and also
