Test on Temperature, Heat, and Thermal Energy

Front

What is potential energy?

Back

Stored energy.

Front

What is heat loss? Give an example.

Back

Heat loss is the transfer of heat from a warmer object to a cooler one. Example: A hot bowl of soup becoming room temperature.

Front

What is heat gain? Give an example.

Back

Heat gain is the absorption of heat by an object. Example: Ice cream melting under the sun.

Front

What energy transformation occurs during radiation?

Back

Radiation is the transfer of energy through electromagnetic waves.

Front

What is convection?

Back

Convection is the transfer of energy due to the movement of matter.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is the difference between temperature and thermal energy?

Back

Temperature measures the average kinetic energy of particles, while thermal energy is the total energy of all particles.

Front

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

Back

The particles move faster and spread apart.

Front

What is the role of insulation in heat transfer?

Back

Insulation reduces heat transfer by conduction, convection, and radiation.
