Gas Laws

Which statement is TRUE if pressure and amount of gas are constant?

• If temperature increases, volume increase

• If temperature increases, volume decreases

200 mL of gas is at 150 K. What is the volume if temperature increases to 300 K at constant pressure?

• 100 mL

• 200 mL

• 400 mL
