The heat at 100C disrupts the ionic bonds, hydrogen bonds and hydrophobic interactions between structural amino acids that make up the enzyme, causing it to be denatured and a loss of 3D conformation and loss of active site. The active site is no longer complementary in shape to the substrate molecules, hence there is no binding of substrate to enzyme.

What happens to the molecules of water when the temperature of the gas cools to 100C?
The molecules slow down and begin to change back to the liquid state.
What is the molecular weight of a compound with pressure 750mm Hg volume 275ml weight 0.920g and temperature of 100c?
In order to find the molecular weight of a compound the components would have to be converted. The conversions are 750mmHg to .987atm, 275ml to .275l, the weight stays at .920g, and the temperature from 100c to 373.15k. These numbers plugged into the equation MW=mRT/(PV) the molecular weight is found to be -.63.
How does the temp of water change as it boils?
Water stays at a constant temperature when it boils unless it is under pressure. More heat just makes it boils faster. The boiling temperature is around 212F or 100C varying somewhat with the altitude and the purity of the water.

Why did the enzyme activity differ at 0c and 100c?
I will assume that you are talking about enzymes found in the normal human body. Enzymes function best at an optimal temperature (in our case, around 37 degrees celsius) because of the inherent tradeoff between reaction rates and protein stability. Remembering your elementary kinetics, the rate of an endothermic reaction (i.e. one that needs energy to function) is directly proportional to the temperature. Since by all means enzymes are biological catalysts, they follow this rule of thumb. However, remembering your biochemistry, higher temperatures lead to protein denaturization, wherein the activity of the enzyme becomes zero due to changes in the protein folding. Thus, in the case of human enzymes, we can expect to see optimal activity at body temp, low activity at lower temperatures, and no activity at very high temperatures.It is important to note though that different enzymes have different optimal temperatures. For example, the DNA polymerase enzyme of Thermophilus aquaticus, a type of bacteria living near volcanic vents has an optimal temperature of around 70-80 degrees celsius!== == the enzymes react faster when the temp. is lower b/c the enzyme would get used to the reaction to keep going and the normal body temp. is closer than 100 degrees celcius>>>......
