Water cycles and processes

Question 1

What is evaporation?

Answer 1

When liquid turns into a gas

Question 2

What is condensation?

Answer 2

When gas turns into a liquid

Question 3

What is latent heat?

Answer 3

When energy is released or absorbed by a body during a process e.g. evaporation/condensation

Question 4

How are clouds formed?

Answer 4

1) water vapour
2) tiny particles e.g. salt and dust called aerosols
3) water vapour and aerosols bump into each other
4) air cools and vapour sticks to aerosols when they collide and condense
5) bigger droplets form around aerosol particles
6) droplets starting sticking to one another forming clouds
7) air becomes saturated and cannot hold anymore water by 1. amount of water in air has increased through evap. 2. air is cooled to dew point.
