100
This type of material keeps heat in.
What is an insulator.
100
This is the direction heat energy moves.
What is from hot to cold
100
This usually happens when heat is added.
What is expansion.
100
This change in state occurs when water reaches 100 degrees Celsius.
What is boiling or condensation.
100

This man created the scale where absolute zero is the lowest temperature.

Who is Lord Kelvin

200

This type of heating does not require using a heat system and relies on the sun to naturally heat a room or house. 

What is passive solar heating

200
These are the two types of transfers required to move heat energy from a liquid to a solid.
What is conduction and convection.
200
This change in volume occurs when heat is removed from a substance.
What is contraction.
200
This is the temperature at which water changes from a liquid to a solid
What is zero degrees Celsius.
200
This is why a lake freezes on the top instead of the bottom.
What is water expands when frozen.
300
This material between two panes of glass makes windows more efficient.
What is still air.
300
This type of energy means "the energy of movement".
What is Kinetic Energy
300
Bridges have metal plates with gaps between them for this reason.
What is the materials expand in the heat.
300
This is the melting point of water.
What is zero degrees Celsius.
300
These are the steps of a experiment write up.
What is problem, hypothesis, materials, procedure, results, conclusion
400
This is a way you could increase the efficiency of a home.
What is add more insulation.
400
Why does conduction happen only in solids?
What is because the particles in a substance need to be touching.
400
Why would a metal toy left in the sun have cracks in the paint?
What is the two different types of metal expand at different rates.
400
This is the number of states a substance can have.
What is three; solid, liquid and gas
400
This is the three ways to increase the speed something changes state.
What is break it up, add other chemicals, add more energy.
500
This form of technology was created to replace boiling water in a bucket over a fire.
What is the electric kettle.
500
This is the only form of energy transfer that happens without molecules.
What is radiation.
500
How could you re-inflate an old balloon?
What is leave it out in the sun.
500
This causes ice to melt.
What is heat energy entering the ice.
500
