Question 4

Boyle’s Law

Answer 4

P1 * V1 = P2 * V2

Question 5

Charles’ Law

Answer 5

V1 / T1 = V2 / T2

Question 6

Gay-Lussac’s Law or Amonton’s Law

Answer 6

P1 / T1 = P2 / V2

Question 7

R value in terms of kPa

Answer 7

8.32 L * kPa/K * mol

Question 8

R value in terms of psi

Answer 8

1.21 L * psi/K * mol

Question 9

Name all postulates of the KMT

SEE TIM

Answer 9

A. Particles move in a STRAIGHT line until they collide with another because no forces are acting on these particles other than their own collisions.
B. Perfectly ELASTIC collisions
C. Particles are smaller than the distance between them, so most of the volume of the gas is EMPTY space.
D. Average kinetic energy depends only on gas TEMPERATURE.
E. No IMFs between gas particles OR between particles and container.
F. Gases are composed of large number of molecules in state of constant, random MOTION.

Question 10

How do nonideal gases behave at high pressures?

Answer 10

Occupy a larger volume

Question 11

Consequences of IMFs

Answer 11

1. ) Gases condense to form liquids at low temperatures (I think this means it is surprising that they condense at all)
2. ) Pressure of a real gas is sometimes smaller than expected for an ideal gas
