Thermal and Kinetic Energy

Front

What is thermal energy?

Back

The total energy of all the particles in a sample of matter.

Front

How does thermal energy move?

Back

Thermal energy always moves from areas of high heat to areas of low heat.

Front

What is kinetic energy?

Back

The energy of an object due to its motion.

Front

What type of material slows the transfer of thermal energy?

Back

Insulators.

Front

What happens to the kinetic energy of molecules as temperature increases?

Back

The kinetic energy of molecules increases as temperature increases.

Front

What is the relationship between temperature and thermal energy?

Back

Higher temperature means higher thermal energy.

Front

If two samples are brought close together, where does heat transfer occur?

Back

Heat transfers from the sample with higher temperature to the sample with lower temperature.

Front

What is an example of a good conductor of thermal energy?

Back

Metals like copper and aluminum.

Front

What is an example of an insulator?

Back

Materials like rubber, wood, and glass.

Front

How does the movement of molecules relate to temperature?

Back

Faster moving molecules indicate a higher temperature.
