Gas Laws: Finding Temperature with Change in Volume and Pressure

CHEM-VSA1MT

A gas has a pressure of 780.00 torr, volume of 30.00 L and is at a temperature of 300.00 K. The pressure changes to 1000.00 torr. The volume changes to 35.00 L.

Which of the following gas laws would be the best choice to use to find the final temperature?

A

Boyle's Law: $P_{1}V_{1}\ =\ P_{2}V_{2}$

B

Charles' Law: $\cfrac{V_{1}}{T_{1}}\ =\cfrac{V_{2}}{T_{2}}$

C

Gay-Lussac's Law: $\cfrac{P_{1}}{T_{1}}\ =\cfrac{P_{2}}{T_{2}}$

D

The Combined Gas Law: $\cfrac{P_{1}V_{1}}{T_{1}}\ =\cfrac{P_{2}V_{2}}{T_{2}}$

E

Avogadro's Law: $\cfrac{V_{1}}{n_{1}}\ =\cfrac{V_{2}}{n_{1}}$

F

The Ideal Gas Law: $PV=nRT$
