In this experiment, the temperature of the gas evolved is equal to the temperature of the water in the beaker, which ideally should be the same as the air temperature. Explain how the volume of oxygen evolved would change if you used ice water instead of room temperature water. How would it change if you used boiling water?

1. What would happen if you added more than 5 mL of yeast to the H2O2?
2. What would happen if you added more than 5 mL H2O2 to the 5 mL of yeast?
3. What was going on in the graduated cylinder as the H2O was pushed out?
4. How would the number of moles (n) of O2 change if your atmosphere was doubled and all other variables stayed the same?
