Final answer:
Increasing the temperature of a container increases gas pressure because it increases the speed and frequency of collisions between gas molecules and the container walls.
Step-by-step explanation:
When the temperature of a container is increased, the kinetic energy of the gas molecules increases. This causes the molecules to move faster and collide with the walls of the container more frequently and with more force, resulting in an increase in pressure. These collisions are known as elastic collisions because no energy is lost during the collision.
For example, let's say we have a container filled with gas molecules. When the temperature of the gas is increased, the molecules gain more kinetic energy. This increased energy causes them to move faster and collide with the walls of the container more frequently. Each time a molecule collides with the wall, it transfers some of its momentum, resulting in an increase in pressure.
Therefore, increasing the temperature of a container increases gas pressure because it increases the speed and frequency of collisions between gas molecules and the container walls.
