Question 66

A gas is contained in a sealed, rigid vessel. The temperature of the gas is decreased.

What happens to the average speed of the gas molecules and what happens to the total internal energy of the gas? (Assume the gas behaves as an ideal gas.)

A

Average speed decreases; total internal energy decreases

B

Average speed decreases; total internal energy remains constant

C

Average speed remains constant; total internal energy decreases

D

Average speed remains constant; total internal energy remains constant
