Pressure - Temperature Relationship Of Gases

Pressure is directly proportional to temperature. This is because according to PV=nRT

Notes:

• The 1000 mL beaker is not necessary, others that can be used are the 600mL and 400mL
• Be Sure to push the stopper on the flask during the hottest test. If you don't the stopper will pop off.

1. What is the graph correspondance to the line? Why is it slightly off?
2. Would the measurments be any different if the container was bigger?
3. Why would the stopper pop off?
4. Why does the temperature increase if the pressure increase? Explain using effective collisions.

Calculations:

1. Calculate the theoretical pressure at 100C or 373K
2. After adding 26.3 grams of N₂ to a 3.4 liter flask it is heated to 56C. Calculate the pressure.
3. Change your answer in part two from atmospheres to kPa and Psi
