What happens when a fixed volume of gas is heated?

What happens when a fixed volume of gas is heated?

When a gas is trapped inside a container which has a fixed size (its volume cannot change) and the gas is heated, the particles will gain kinetic energy which will make them move faster.

What happens if a gas is heated?

When you heat a gas, both its vapor pressure and the volume it occupies increase. The individual gas particles become more energetic and the temperature of the gas increases. At high temperatures, the gas turns into a plasma.

What happens when a gas is heated or cooled?

If a gas is cooled, its particles will eventually stop moving about so fast and form a liquid. This is called condensation and occurs at the same temperature as boiling. Hence, the boiling point and condensation point of a substance are the same temperature.

How long should you keep a warm compress on your eye?
