Thermal Energy Transfer in Systems

Front

The movement of thermal energy from a region of higher temperature to a region of lower temperature is called:

Back

Heat

Front

The transfer of energy through direct contact between molecules is known as:

Back

Conduction

Front

The transfer of energy by electromagnetic waves is referred to as:

Back

Radiation

Front

In a lava lamp, the warm part rises and the cool part sinks. This process is an example of:

Back

Convection

Front

What is the difference between heat and temperature?

Back

Temperature measures the motion of molecules, and heat is the energy of that motion.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.
