What is heat? Heat is a form of energy.
Give an example of heat being converted into another form of energy. Light bulbs heat up a filament until it glows and gives off light.
What is temperature? Temperature is what we use to measure the levels of heat in a substance.
What instrument measures temperature? A thermometer.
Explain the difference between temperature and heat. Temperature is the numerical measure of heat. Heat is the form of energy.
What is the boiling point and melting point of water. Boiling: 100°C Melting: 0°C
What happens when substances change state? It has to take in or give off energy to change to either a liquid, solid, or gas.
What happens when substances change state? When a substance looses enough heat energy it will change to a solid instead of a liquid.
What is condensation? Condensation is when a vapour comes in contact with a cold surface or other gas and becomes a liquid
What is Latent heat? Latent heat is heat that is left inside a substance and has not been able to cool fully.
How can you identify Latent heat on a graph? The graphs curve will go flat before dropping temperature once the latent heat is gone.
What is an insulator? An insulator is something that stops or reduces heat transfer from one substance to another.
Define the terms conduction. Conduction is heat transfer through physical contact.
Define the terms convection. Convection is heat transfer through a gas.
