Evaporation & Condensation
- Example of Evaportation: When you hang wet
clothes onto a washing line, they will
gradually dry off. This happens in a process
called evaporation.
- What is evaporation???
- Evaporation is the process when water molecules
escape from the surface of the water and enter the
air.
- Definition of evaporation:
Evaporation is when liquid turns to
gas.
- Definition of evaporation:
Evaporation is when liquid turns to
gas.
- Evaporation is the process when water molecules
escape from the surface of the water and enter the
air.
- What is evaporation???
- Example of Condensation: In a steamy
bathroom, a mirror is often covered with a film of
water. As there are lots of water molecules in the
air, some of them hit the mirror, cool down and
stay there. This is a process called condensation.
- What is condensation???
- Definition of
condensation:
Condensation is when
a gas turns to a liquid.
- Definition of
condensation:
Condensation is when
a gas turns to a liquid.
- What is condensation???
- Cooling by evaporation: what is it???
- Example of Cooling by Evaporation: When you are at the
doctor before an injection the nurse may 'numb' your skin
so you don't feel any pain, by dabbing a liquid that
evaporates easily onto your skin. The liquid will evaporate
and your skin will feel to cold to feel pain.
- How does it work: The coolinh by
evaporation of a liquid is all down to the
fast moving molecules escaping from the liquid.

- There are ways of which we can increase the speed of these two processes.
- Evaporation can be increased by:
- 1) Increasing the surface area of the liquid
- 2) Increasing the temperature of the liquid
- 3) Creating a draught of air across the liquids surface
- 1) Increasing the surface area of the liquid
- Condensation can be increased by:
- 1) Increasing the surface area
- 2) Reducing the surface temperature
- 1) Increasing the surface area
- Evaporation can be increased by:
