Asample of gas is enclosed in a container of fixed volume.

I am unsure if this is correct (especially since I'm answering late), but here is the possible full question:

A sample of gas is enclosed in a container of fixed volume. Identify which of the following statements are true. Check all that apply.

O If the container is heated, the gas particles will lose kinetic energy and temperature will increase.

O If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.

O If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.

O If the gas particles move more quickly, they will lose energy more rapidly and collide with the walls of the container less often, and pressure will decrease.

O If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.

The answers to this question are If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease., If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase., and If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase. (2nd, 3rd, and 5th options).

beta decay is the answer
