Understanding Temperature and Pressure in Gases

In Year 8 Chemistry, it’s important to know how temperature and pressure affect gases. These two things are key to understanding how gases act.

What is Temperature?

Temperature tells us how fast gas particles are moving on average. When the temperature goes up, the gas particles speed up. Here’s what happens when temperatures change:

• Higher Temperatures: When it’s hotter, gas particles get more energy. This makes them move around more. Because they are moving faster:
  • Pressure Increases: If the amount of space (or volume) the gas is in stays the same, the faster particles bump into the walls of their container more often and with more force. This leads to higher pressure in the container.

Remember, temperature is all about how quickly those tiny gas particles are moving!
