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
25*C + 273 =
What is 298K in Celsius?
200
This is a common way to cool a home.
What is an air condition (forced air system)?
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 is what happens first between cold air descending and hot air rising.
What is cold air descends?
200
This is the temperature at which water changes from a liquid to a solid
What is zero degrees Celsius.
200
This is 70*C converted to K.
What is 343 K?
300
From hot to cold.
How does energy (heat) flow?
300
This type of energy means "the energy of movement" and is proportional to temperature .
What is Kinetic Energy?
300
Bridges have metal plates with gaps between them for this reason (particles moving faster).
What is the materials expand in the heat?
300
This is the melting point of water.
What is zero degrees Celsius.
300
This is -15*C converted to K.
What is 258 K?
400
This is the temperature flow of energy.
What is from high to low temperature?
400
This type of energy transfer only occurs in solids touching other solids.
What is conduction?
400
the symbol for heat
What is Q?
400
This is the number of states a substance can have.
What is three; solid, liquid and gas
400
This is 200 K written as Celcius.
What is 73*C?
500
This is why a hot air balloon rises.
What is cold air condenses, sinks and forces less-dense hot air to rise?
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 or add heat?
500
This causes ice to melt.
What is heat energy entering the ice.
500
This is -15 K written in Celcius.
What is -288 K
