Final answer:
Increasing the temperature of the gas in a box leads to an increase in the motion of the particles and subsequently increases the pressure. The particles move faster and collide with the walls of the container more frequently and more forcefully.
Step-by-step explanation:
When the temperature of the gas in a box is increased, the motion of the particles also increases. The particles move faster and collide with the walls of the container more frequently and more forcefully.
This increase in motion and collisions increases the pressure inside the box. This is because the particles exert a force on the walls of the container each time they collide with it, and as the number and force of collisions increase, so does the pressure.
For example, if we imagine a gas inside a balloon, when the gas molecules heat up and move faster, they strike the inside wall of the balloon harder. This increased motion and force of the gas particles leads to a rise in pressure inside the balloon.
