Water in the atmosphere Flashcards
1
Q
What happens to heat as water evaporates and condenses?
A
When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.
2
Q
What three states does water exist in?
A
Solid
Liquid
Vapour
3
Q
What is condensation?
A
If saturated air is cooled, the water vapour content will become too great, and visible droplets will appear.
During condensation, latent heat is released, causing atmospheric warming.
4
Q
What is sublimation?
A
Sublimation is the process where ice and snow (solid) changes into water vapour (gas) without moving through the liquid stage.
5
Q
Name the heat required to cause a change in state?
A
Latent heat
6
Q
What instrument is used to measure humidity?
A
Hygrometer
