Key Stage 2

Meaning

Condensing is when a gas turns into a liquid.

Noun: Condensation
Verb: To condense
Present Participle: Condensing
When you cool a gas:
 
A gas will condense to become a liquid.

About Condensing

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.

Key Stage 3

Meaning

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

About Condensing

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.
