decreased, the gas temperature

• Increases.

• Stays the same.

• Decreases.

• Not enough information

  to tell.

Two identical cylinders, A and B, contain the same type

of gas at the same pressure. Cylinder A has twice as

much gas as cylinder B. Which is true?

• T_A < T_B

• T_A = T_B

• T_A >T_B

• Not enough information

  to make a comparison.

Two cylinders, A and B, contain the same type of gas at the

same temperature. Cylinder A has twice the volume as

cylinder B and contains half as many molecules as cylinder

B. Which is true?

• p_A = 4p_B

• p_A = 2p_B

• p_A = p_B

• p_A = 1/2p_B

The temperature of a rigid (i.e., constant-volume),

sealed container of gas increases from 100C to

200C. The gas pressure increases by a factor of

• 2

• 1.3

• 1 (the pressure doesn’t change).

• 0.8

• 0.5

A cylinder of gas has a frictionless but

tightly sealed piston of mass M.

A small flame heats the cylinder,

causing the piston to slowly move

upward. For the gas inside the

cylinder, what kind of process is this?

• Isochoric.

• Isobaric.

• sothermal.

• Adiabatic.

• None of the above

A cylinder of gas has a frictionless

but tightly sealed piston of mass M.

The gas temperature is increased

from an initial 27C to a final 127C.

What is the final-to-initial volume

ratio Vf /Vi?

• 1.50

• 1.33

• 1.25

• 1.00

A cylinder of gas floats in a large tank of water. It has a

frictionless but tightly sealed piston of mass M. Small

masses are slowly placed onto the top

of the piston, causing it to slowly move

downward. For the gas inside the cylinder,

what kind of process is this?

• Isochoric.

• Isobaric.

• Isothermal.

• Adiabatic.

• None of the above.

What type of gas process is this?

• Isochoric.

• Isobaric.

• Isothermal.

• Adiabatic.

• None of the above.

A gas follows the process shown. What is

the final-to-initial temperature ratio T_f /T_i?
