Thermal Energy Transfer

Front

What is the process by which heat is transferred through electromagnetic waves?

Back

Radiation.

Front

What type of heat transfer occurs when two objects are in direct contact?

Back

Conduction.

Front

What is the term for the movement of thermal energy through fluids (liquids and gases)?

Back

Convection.

Front

How is temperature defined in terms of particle motion?

Back

Temperature is a measure of the average kinetic energy of the individual particles in an object.

Front

What is the primary source of radiation that heats the Earth?

Back

The Sun.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

What happens to the particles in a substance as it is heated?

Back

The particles gain kinetic energy and move faster.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature.

Front

What is the role of insulators in thermal energy transfer?

Back

Insulators reduce the transfer of thermal energy.

Front

What is an example of conduction in everyday life?

Back

A metal spoon getting hot when placed in a pot of boiling water.
