Heat and Energy Transfer

Front

What is the process called when heat is transferred through the movement of fluids (liquids or gases)?

Back

Convection

Front

In thermal energy transfer, heat flows from which type of object to which type of object?

Back

Heat flows from the warmer object to the cooler object.

Front

What happens to the motion of molecules as the temperature of a substance increases?

Back

The molecules move faster.

Front

What is the relationship between the speed of an object and its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

When you touch a hot stove, in which direction does the heat transfer occur?

Back

Heat transfers from the stove to your hand.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects reach the same temperature and no heat flows between them.

Front

What is conduction?

Back

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

Front

What is radiation in the context of heat transfer?

Back

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

Front

What is the primary factor that affects the rate of heat transfer by conduction?

Back

The temperature difference between the two objects.

Front

What is the role of a conductor in heat transfer?

Back

A conductor is a material that allows heat to pass through it easily.
