Question

When a gas is heated, the following statements is true: a) The molecules increase in volume b) The molecules collide with the walls of the container less frequently c) The molecules collide with each other less frequently d) The molecules increase in velocity e) None of the above

Answer 1

When gas is heated the volume of the gas expands but the volume of the gas molecules does not increase.

As the molecules get more energy from heating, the velocity increases. As the velocity increases, the molecules can collide with each other more frequently.

true response is:

(d)
