WOW #12 Intro to Thermal Energy

Front

What happens to a substance when thermal energy is removed from it?

Back

The substance might freeze.

Front

Why do atoms have kinetic energy?

Back

Because they are always vibrating.

Front

What is conduction?

Back

The transfer of energy from one particle of matter to another within an object or between two objects that are in direct contact.

Front

What type of chemical reaction can be used to heat up other substances?

Back

A chemical reaction that releases energy.

Front

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

Back

The temperature increases.

Front

What is thermal energy?

Back

The total kinetic energy of all the particles in a substance.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids and gases).

Front

What is radiation in terms of thermal energy?

Back

The transfer of energy by electromagnetic waves.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of the molecules increases.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a hot soup.
