Science - Heat
What is heat?
Heat is a form of energy
State the three different ways heat can move
What is a conductor? Give an example
A conductor is a material that allows heat to pass through to eg. copper, aluminium and brass
What is an insulator? Give an example
An insulator is a material that does not allow heat to pass through it eg. a lagging jacket, clothes and fibreglass
This is the way heat moves through a material without the material moving eg. along a metal spoon
What is convection?
This is the movement of heat in liquids and gases by flowing currents eg. heating water in a kettle
This is the movement of heat in rays eg. the sun and the grill
State the temperature water boils at
Do bright surfaces reflect or absorb heat?
Reflect the heat
Do dark surfaces reflect or absorb heat?
Absorbs the heat
What happens to a solid, liquid or a gas when it is heated?
What happens to a solid, liquid or gas when it is cooled?
What is temperature?
This is a measure of how hot or cold an object is
State the piece of equipment used to measure temperature
State the SI unit used to measure temperature
Degrees Celsius (
Explain the difference between heat and temperature
Heat is a form of energy whereas temperature is a measure of how hot or cold an object is
State the SI unit used to measure heat
Explain latent heat
Latent heat is the energy needed to change the state of a substances without changing its temperature
