Back

Heat

Front

Which process involves heat being transferred through direct contact between materials?

Back

Front

What happens to heat flow when an ice cap melts?

Back

Heat flows from the water to the icecap.

Front

What occurs to the temperature of water when ice cubes are added?

Back

The temperature decreases because some of the water's heat is lost to the ice.

Front

What is thermal energy?

Back

The total kinetic energy of particles in a substance.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred due to temperature difference, while temperature is a measure of the average kinetic energy of particles.

Front

What is convection?

Back

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

Front

What is radiation in terms of heat transfer?

Back

The transfer of heat through electromagnetic waves, such as sunlight.
