Unit 3: Energy and Energy Transformations Review

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What type of energy is stored when you stretch a rubber band?

Back

Potential energy.

Front

What is convection?

Back

Convection is the transfer of heat through currents in fluids (liquids and gases).

Front

Give an example of conduction in everyday life.

Back

Ironing a shirt is an example of conduction.

Front

What is the transfer of heat energy through direct contact called?

Back

Conduction.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight.

Front

How does heat transfer occur in liquids and gases?

Back

Heat transfer in liquids and gases occurs through convection.

Front

What happens to particles in a substance when it is heated?

Back

The particles move faster and spread apart, increasing the substance's temperature.
