6.1 Heat and Energy Transfer

Front

What is heat transfer?

Back

The process of thermal energy moving from one object to another due to a temperature difference.

Front

What happens when two objects at different temperatures come into contact?

Back

Heat flows from the warmer object to the cooler one until they reach the same temperature.

Front

Define conduction.

Back

The transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

Define convection.

Back

The transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

What is a conductor?

Back

Materials that transfer energy, especially heat, efficiently.

Front

What is an insulator?

Back

Materials that do not transfer energy well, preventing heat flow.

Front

What is thermal equilibrium?

Back

The state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is the role of temperature in heat transfer?

Back

Temperature determines the direction of heat flow; heat moves from higher to lower temperature.

Front

What is the difference between heat and temperature?

Back

Heat is the total energy of molecular motion in a substance, while temperature is a measure of the average energy of that motion.
