Phase Change Flashcards
What is the process from a liquid to a solid?
The liquid is freezing into a solid.
What is the process from a solid to a liquid?
The solid is melting into a liquid.
What is the process from a liquid to a gas?
The liquid is vaporizing into a gas.
What is the process from a gas to a liquid?
The gas is condensating into a liquid.
What is the process of a gas to a solid?
The gas is depositing into a solid.
What is the process of a solid to a gas?
The solid is sublimating into a gas.
What is endothermic?
Endothermic: Absorbs energy
What is exothermic?
Exothermic: Releasing energy
What is the process of freezing?
- Exothermic
- it’s the same temperature as the melting point
What is the process of vaporization?
- Endothermic
- takes place at the surface of the liquid
- during evaporation surface particles are hit and give them enough energy to turn into a gas.
What is the process of boiling?
- turns into gas below the surface
- particles gain energy
- the temperature at which a liquid boils depends on the temperature and pressure of the liquid
Why does steam appear on the mirror after you shower?
Steam appears in the mirror because when the warm humid air hits the cold mirror surface it loses energy. The particles slow down and droplets form on the mirror.
Why is being burnt by steam more damaging than being burnt by water?
Being burnt by steam or a gas is more damaging because the gas has a higher amount of energy than the water therefore it damages more.
Describe the changing process of phase change for water:
0 and below Celsius - solid
Melting pint is at 0
Boiling point is at 100
Steam is created from 100 and up
