Answers
1
Which one is Boyle's Law?
P ∝ V
T ∝ V
P ∝ 1/V
P ∝ T
2
How is temperature related to pressure?
P ∝ T
P ∝ V/T
P ∝ 1/T
1/P ∝ T
3
What is GL's Law?
P1/P1 = T1/T2
P1P2 = T1T2
P1T1 = P2T1
P1/T1 =P2/T2
4
Which equation can we use to calculate the new volume or pressure of a gas at fixed mass?
P1V1 = P2V2
P1P2 = V1V2
P1V2 = P2V1
P2V1 = P1V2
5
What is absolute zero?
When particles no longer have kinetic energy
When matter becomes solid
When particles no longer exert any pressure
When water freezes
6

273 K
0 K
-273 oC

293 oC
25 oC
293 K
273 K
