Which of the following occurs when the temperature of a gas rises?
I.The kinetic activity of the gas increases.
II.The rate of molecular collisions increases.
III.The pressure exerted by the gas rises.

Question

Quizplus · Accepted Answer

When the temperature of a gas increases, the average kinetic energy of its molecules also increases. This means that the speed and kinetic activity of the gas also increase, leading to an increase in molecular collisions (as molecules move faster they collide with each other more frequently). These collisions result in a higher pressure being exerted by the gas. Therefore, all three options are correct: I. The kinetic activity of the gas increases, II. The rate of molecular collisions increases, and III. The pressure exerted by the gas rises.
