Question

The kinetic molecular theory predicts that the pressure rises as the temperature of a gas increases because:

Answer 1

The correct answer is

e. both c and d above are true.

In fact, the kinetic molecular theory predicts that when the temperature of a gas increases, the speed of the molecules increases. This means that the particles are more energetic and move faster, and there are two consequences of this:

1) Since the molecules move faster, they collide more frequently with the walls of the container (option c)

2) Since the molecules are more energetic, they collide more energetically with the walls of the container (option d)

As a result, the pressure of the gas increases. So, both options c and d are correct.
