This theory helps explain some physical properties of matter, like temperature and state.
What is the KINETIC THEORY OF MATTER?
100
Material that resists the transfer of heat.
What is an INSULATOR?
100
Which would have a higher temperature, an ice cube or boiling water?
What is BOILING WATER?
100
Thermal energy depends on these 2 factors.
What is TEMPERATURE & MASS?

Classify if these are CONDUCTORS or INSULATORS:
Copper pipes, Oven mitt, Sweater, Baking Sheet, Frying Pan Bottom, Frying Pan Handle
Conductors: Copper pipes, Baking Sheet, Frying Pan Bottom
Insulator: Oven Mitt, Sweater, Frying Pan Handle
200
Transfer of energy through fluids like gas or liquid.
What is CONVECTION?
200
The state when the transfer of heat between 2 objects ceases.
What is THERMAL EQUALIBRIUM?
200
Which would have more thermal energy, a pot of boiling water or an iceberg?
What is an ICEBERG? (More potential energy of particles)
200
Draw particles from a solid state, liquid state, and gaseous state.
Pg 93
200
These could be great insulators for homes in Michigan.
What are Foam, Double Glazed Windows (pg115), Fiberglass, and Plastics?
300
Transfer of thermal energy through electromagnetic waves.
What is RADIATION?
300
Material that conducts heat easily, like metal.
What is a CONDUCTOR?
300
If you had equal amounts of water molecules in the following states: liquid, steam/gas, ice, which has the highest amount of thermal energy?
What is the GAS/STEAM?
300
Can heat be transferred between gases?
What is NO?
300
Why does insulation help homes in winter and summer?
What is because the insulation prevents warming from the outside in summer, and traps heat within the home in the winter?
400
Total amount of potential and kinetic energy in all the particles in a substance.
What is THERMAL ENERGY?
400
The measure of the average kinetic energy of the particles in a substance.
What is TEMPERATURE?
400
This is how cold milk cools coffee.
What is that the hot molecules in the coffee transfer their energy to the cooler molecules, warming them. The mixture will eventually hit thermal equalibrium, where the temperature is between the 2 original liquids.
400
This remains the same during evaporation.
What is AVERAGE KINETIC ENERGY (TEMP)?
400
Microwaves heat food in this manner.
What is RADIATION?
500
When particles on the surface of a liquid gain enough heat energy to leave the surface of a liquid.
What is EVAPORATION?
500
The transfer of thermal energy between 2 objects that are touching.
What is CONDUCTION?
500
There is a pot of boiling water, and more heat is added. Explain what happens.
What is a CHANGE OF STATE? (Liquid to Gas)
500
Draw the phase change diagram.
