atmospheric pressure

The temperature at which a liquid starts boiling at the ________ is known as its boiling point.

minimum temperature

The ________ at which a solids melts to become a liquid at the atmospheric pressure is called its melting point.

kinetic energy

gaseous state

In the ________, the particles move about randomly at high speed.

Liquids flow

________ and change shape, so they are not rigid but can be called fluid.

energy

The ________ supplied by heat overcomes the forces of attraction between the particles.

surface area

If the ________ is increased, the rate of evaporation increases.

solid melts

A stage is reached when the ________ and is converted to a liquid.

Solid CO2

________ gets converted directly to gaseous state on decrease of pressure to 1 atmosphere without coming into liquid state.

Solid carbon dioxide CO2

________] is stored under high pressure.

heat energy

The ________ equal to the latent heat of vaporisation is absorbed from the body leaving the body cool.

Particles of matter

________ are continuously moving, that is, they possess what we call kinetic energy.
