Thermal Energy and Heat Transfer Exam

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy, usually in the form of heat, to its surroundings.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, often resulting in a temperature drop.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, which is related to its temperature.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

Conduction is the transfer of heat through a solid material without any movement of the material itself.

Front

Define convection.

Back

Convection is the transfer of heat through a fluid (liquid or gas) caused by the movement of the fluid itself.

Front

Define radiation.

Back

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

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking, creating a circulation pattern.
