Question

when a gas is heated in a container the pressure increases.explain using the particle theory of matter

Answer 1

Answer:

The expansion of the gases and liquids is because the particles are moving around very fast when they are heated and are able to move further apart so they take up more room. If the gas or liquid is heated in a closed container, the particles collide with the sides of the container, and this causes pressure.

Answer 2

Answer:

When you heat the molecules they get more energy and impact on wall of container with more velocity so pressure increases .

In a container volume is constant . You can use

PV =nRT for ideal gases . n , R and V are constant so when T increases P also increases.
