The types of particles that exist in a copper wire
Atoms
The process involved during hair drying
Evaporation
The changes in the movement of water particles when hair is dried
Water particles move freely more quickly
Sublimation
A process of conversion of a substance from the solid to the vapour state without its becoming liquid
Condensation (1)
A process by which a gas or vapour changes to liquid state at a certain temperature
Condensation (2)
When the temperature drops, the gas loses its kinetic energy, and therefore it will change the physical state of matter to the liquid
Condensation (2)
Condensation occurs at or below the boiling point of the substance
Freezing (1)
Temperature drops and the heat energy is released
Freezing (2)
As the heat is released, the kinetic energy decreases, the movement of particles are slower and the particles are pulled closer by the strong forces between particles
Freezing (3)
The temperature stays at the freezing point because the heat is released constantly
