Condensing is when a gas turns into a liquid.

Noun: Condensation

Verb: To condense

When you cool a gas:

A gas will condense to become a liquid.

Cooling a gas will cause it to condense into a liquid.

Condensing is a reversible process. When a gas condenses into a liquid you can evaporate that liquid back into a gas.

You may have seen water condensing.


Water Vapour in the air condenses into liquid water onto a cold bottle.	The Steam coming out of kettle condenses into a cloud of liquid water droplets.

Condensing is an exothermic process in which a gas turns into a liquid.

Condensing is a reversible process. When a gas condenses into a liquid you can evaporate that liquid back into a gas.

Cooling a gas will cause it to condense into a liquid.

When you cool a gas:

The particles in the gas slow down until they are slow enough that forces between the particles start to hold them together. The particles end up touching but can still move past each other which makes the state a liquid.

Condensing happens when the particles in a gas form bonds holding them together as they lose potential energy.

The temperature at which a substance condenses is the same as the temperature at which it boils so it is the boiling point.

Condensing is an exothermic process, which means it emits energy when it takes place.

Condensing is a physical change, which means it is reversible and does not produce new chemicals.


As energy is removed from the liquid it freezes and the temperature of the substance stays the same.
