Thermal Energy Intro

At higher temperatures

• particles in an object have less energy
• particles in an object move faster
• a gas contracts

A gas

• has a definite shape but no definite volume
• has a definite volume but no definite shape
• has fast-moving particles

Particles of a liquid

• are tightly packed together and stay in a fixed position.

• are free to move around one another but still touch.

The thermal energy transfer being shown in this image is...

• conduction

• convection

• radiation

The heat from a lamp allows a lizard to remain warm. This is an example of which type of heat transfer?

• radiation

• conduction

• convection

What is a conductor?

• Material that does NOT transfer energy.

• Materials that are connected to circuits.

• Materials that transfer energy.

• Materials that

A great conductor of energy is:

• wood
• plastic
• metal
• cloth

What is NOT an example of an insulator in the kitchen?

• An oven mitt
• Pots and pans
• A wooden spoon
