1650 - What is the significance of the temperature T in the ideal gas equation PV=nRT?

The 'T' in the ideal gas equation PV=nRT is a very important part. It represents the temperature of the gas in Kelvin (K).

When the temperature of the gas goes up, the gas molecules start moving faster and spreading out. This makes the pressure of the gas increase.

In the equation, if 'n' and 'R' are constant, then you can see that 'P' and 'T' are directly proportional (or connected). This means if 'T' goes up, 'P' will also go up, and if 'T' goes down, 'P' will also go down.

Think of it like blowing air into a balloon. As you warm up the air (increase the temperature), the air molecules in the balloon move faster and faster, making the balloon bigger and more pressurized.
