Boyle's Law

Charles's Law

Ideal Gas Law

Combined Gas Law

What is the correct formula for Boyle's Law?

V₁/T₁=V₂/T₂

P₁V₁=P₂V₂

32.5 mL

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

Three gases, Ar, N₂ and H₂ are mixed in a sealed container. Ar has a pressure of 255 torr, N₂ has a pressure of 228 torr and H₂ has pressure of 752 torr. What is the total pressure in the container?

483 torr

270 torr

1235 torr

760 torr

Determine the initial temperature of a random gas when the initial volume is 2.2 L and it is cooled to 88K with a volume of 0.85 L.

0.029 K

0.021 K

227.76 K

34 K

What is the equation to solve for Charles' Law?

P1 (P2) = V1 (V2)

V1 / T1 = V2 / T2

P1 / T1 = P2 / T2

V1 / V2 = T1 / T2

What is the equation to solve for Gay Lussac's Law?

P1 (P2) = V1 (V2)

V1 / T1 = V2 / T2

P1 / T1 = P2 / T2

V1 / V2 = T1 / T2
