Q)what happen when liquid is heated?
.



Q)A gas can exert pressure on the walls of the container . Assign reason.​

Answer 1

Answer:

As a liquid is heated, its molecules absorb heat and move faster. When the liquid starts to boil, bubbles of vapor form within the liquid and rise to the surface. The temperature that causes this to happen is known as the boiling point of a liquid. ... When a liquid is heated, molecules move faster.

Explanation:

The pressure exerted by a gas is due to the random motion of particles in the gas. Gases have weak intermolecular forces and the particles in continuous random motion and these particles collide with the walls of the container. These collisions with the walls of the container exerts pressure on the gas.

Question

A gas can exert pressure on the walls of the container . Assign reason.

Answer

The molecules are continually colliding with each other and with the walls of the container. When a molecule collides with the wall, they exert small force on the wall The pressure exerted by the gas is due to the sum of all these collision forces.
