Question

A high-temperature gas is compared to the same gas at lower temperature. Which of the following statements is true?


A. Every molecule in the high-temperature gas is moving faster than every molecule in the low-temperature gas.

B. The average molecular speed in the high-temperature gas is faster than the average molecular speed in the low-
temperature gas.

C. Both A and B are true.

D. Neither A nor B is true.

Answer 1

Answer:

I think it is C

Explanation:

If the temperature of a gas increases, the gas particles have a higher average speed as they gain kinetic energy. They collide more frequently with the walls of the container, which produces a bigger pressure.
