You have a gas that has a pressure of 2 ATM and a volume of 10L.  What would be the new volume if the pressure was changed to 1 ATM?

• 5 L
• 20 L
• It would stay at 10L
• 1 L

If a gas is measured to have a volume of 0.5atm at 273K, what would happen to the pressure if the temp increased to 300K?

• increase

• decrease

• remain the same

A balloon is filled with 1.9 moles of He at 45C. WHat would happen to the pressure in the balloon if 0.20moles of He are removed at the same pressure?

• increase

• decrease

• remain the same
