2 1 states of matter

The interconversion that takes place when a liquid becomes a solid is called freezing.

The type of energy that allows particles to move in the liquid state is kinetic energy.

Sublimation is when a solid changes directly into a gas.

The solid state state has particles very close together that vibrate about a fixed position.

False. Particles in a liquid have restricted movement and move around each other. Gas particles move quickly in all directions.

False. Energy is released when a gas changes into a liquid.

True. There is no difference between the melting point and freezing point.

When a solid turns to a liquid, the forces of attraction are overcome or broken.

True. The three states of matter are solids, liquids and gases.

Melting is when a solid changes into a liquid.

Boiling is when a liquid changes into a gas at a specific temperature.

Freezing is when a liquid changes into a solid.

Evaporation is when a liquid changes into a gas.

Condensation is when a gas changes into a liquid, usually on cooling.

Interconversion of state is the change of matter from one state to another due to changes in temperature or pressure.
