Thermal Energy & Heat Review

Front

What is thermal energy?

Back

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

Front

What is heat?

Back

Heat is the transfer of thermal energy from a warmer object to a cooler object.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

How does heat transfer occur in a microwave?

Back

Heat transfer in a microwave occurs through radiation, as microwaves excite water molecules in the food.

Front

What happens to ice cream on a hot day?

Back

Heat moves from the hot air to the ice cream, causing it to melt.

Front

What is the relationship between heat and temperature?

Back

Heat is the energy transferred due to temperature differences, while temperature measures the average kinetic energy of particles.
