Unit 5 - Thermal & Kinetic Energy - 7th Science

Front

Name the type of heat transfer.

Back

Convection

Front

What is the definition of CONVECTION?

Back

When heat is transferred by movement of gas or liquids. It is also when gas/liquid becomes less dense and rises or becomes more dense and sinks.

Front

As velocity (speed) increases, kinetic energy ___________.

Back

increases

Front

Radiation is __________.

Back

thermal energy transfer by rays and waves in empty space.

Front

Energy produced by electromagnetic waves is called __________.

Back

radiant energy.

Front

What is conduction?

Back

Thermal energy transfer in solids by direct touch.

Front

What is convection?

Back

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

Front

What happens to the kinetic energy of an object when its mass increases, assuming speed remains constant?

Back

The kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy = 1/2 * mass * velocity^2.

Front

What is thermal energy?

Back

The total energy of all the particles in an object.
