Do molecule move faster in solids or gases?
Gases
100
These resources come from the remains of plants and animals.
Fossil Fuels
100
Heat always transfers from ______ to _______ surfaces.
Warm to cold
100
Wood is a(n) ______ while metal is a blank _______.
insulator, conductor
200
A boy on a bike is stopped at the top of a hill. What kind of energy does he have?
Potential
200
What do coal, oil, and natural gasses have in common?
They are all nonrenewable resources
200
Pressing a hot iron onto your clothes is an example of which types of heat transfer?
Conduction
200
A heater creates this.
Convection Current
300
Energy is the ability to bring about changes or ______.
Do work
300

Pressing the brakes on your bike creates this force.

Friction 
300
Why does hotter air rise while cooler air falls?
Because the molecules in hot air spread out and become less dense. Less dense fluids rise. 
300
The chocolate melting i your solar ovens was an example of this type of heat transfer.
Convection
400
How does energy transfer  from a warmer object to a cooler object?
Heat Flow
400

Name a renewable resource that comes from plant and animal materials.

Biomass Conversion
400
What is the force called that acts in the opposite direction of gravity?
Buoyancy
400
______ is measured in Calories.
Heat
500
Describe how a thermometer works in relation to movement of molecules.
The molecules surrounding the thermometer are moving at a specific rate. Kinetic energy is transferred from these molecules to the molecules inside the thermometer, causing them to spread out (increase temp) or condense (decrease temp). 
500
Which force can be used to generate heat?
Friction
500
How does buoyancy relate to density?
The less dense something is, the more buoyant it will be. (example: oil and water)
500
What does the word vacuum have to do with insulation.
Having a vacuum on a water bottle means there is some sort of empty space between layers of the water bottle so the bottle conducts less heat.
