* Kinetic Energy: The temperature of a gas is directly related to the average kinetic energy of its molecules. Kinetic energy is the energy of motion.
* Heat Transfer: When you add heat to a gas, you are transferring energy to its molecules.
* Increased Motion: This added energy causes the molecules to move faster, resulting in a higher average speed.
Think of it like this: Imagine the molecules of a gas as tiny balls bouncing around in a container. When you heat the container, you are giving the balls more energy. This causes them to bounce around more vigorously, leading to a higher speed.
Important Note: The speed of individual molecules in a gas is constantly changing due to collisions. However, the average speed of the molecules increases as the temperature increases.
