What is conduction.
Substances that reduce the transfer of thermal energy.
What are insulators.
If two objects have different temperatures, in which direction will heat move? When will the heat stop moving?
hot to cold untill equall
What is convection?
Answers vary. Sunlight, heat from fire, etc.

What are conductors
The name of the variable you change in an experiment
What is the independent/manipulated variable.
What are the 3 ways thermal energy can be transferred?
Conduction, Convection and Radiation
Heat transfer caused by rising of hot, less dense materials and falling of cooler, more dense substances.
What is convection.
Energy stored in a system.
What is potential energy.
This is anything that has mass and takes up space.
What is matter
This is when thermal energy is transferred between two objects
What is heat

Alcohol.
State the law of conservation of energy.
Energy cannot be created or destroyed. Only changes forms.
