When the temperature is increased, the speed of gas molecules increases. This is because as the temperature rises, the molecules gain more kinetic energy, leading them to move faster. In other words, the average speed of gas molecules is directly proportional to the temperature.
Here's a simple breakdown to explain this concept:
1. When you heat a gas, its molecules absorb energy.
2. This absorbed energy causes the molecules to move faster and collide with each other and the container walls more frequently.
3. As a result, the speed of the gas molecules increases with the temperature.
Therefore, when the temperature is increased, the speed of gas molecules increases as well.
