Total force
Conductivity is a measure of
The rate at which heat travels along an object
The energy required to turn a liquid into a solid
Latent heat of fusion
What happens to temperature when an object changes state
Temperature does not change
Convection occurs when
Air is heated and rises
Thermals
Naturally occurring convection currents
Dark rough surfaces absorb ________ than they reflect and are ________ radiators
More radiation
Good radiators
Light shiney objects reflect _______ than they absorb and are _________ radiators
More radiation
Poor radiators
Convection occurs in
Gas & liquid
Conduction occurs in
Solid objects
Conduction
vibrating atoms in the hotter object pass energy to the cooler neighbouring atoms in the other object
Insulation
Reduces the flow of heat & can be used to keep things hot or cold
Temperature
A measure if the average kinetic energy of the particles in the substance
Kinetic model explains
The properties of the different states of matter
