Gas laws

1. A sample of helium gas occupies 11.6L at 23OC and 0.956 atm. What volume will it occupy at 40oC and the same pressure?

2. Determine the pressure exerted by 4.58 mol of a gas in a 2.92L container at 32oC?

3. You are playing with a helium balloon on a typically nice fall day in Fullerton; CA. Suddenly the Celsius temperature doubles. How would the volume inside the balloon change?

4. A certain balloon will pop if it expands to a volume greater than 16.0L. The balloon is currently filled with air at a volume of 8.0L. You heat the balloon to double its original temperature in Celsius. Will the balloon pop?

5. Consider a gas at 1.00 atm in a 5.00 L container at 20OC. What pressure does the gas exert when transferred to a volume of 3.53 L at 43OC?
