Heat Transfer Flashcard Review

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 main types of heat transfer?

Back

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

Front

Define conduction.

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

Define convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, which can occur in a vacuum.

Front

What happens to particles in a substance when it is heated?

Back

When a substance is heated, its particles gain kinetic energy and move faster, causing the substance to expand.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot pot of soup.

Front

What is an example of convection in everyday life?

Back

An example of convection is the warm air rising from a heater and circulating around a room.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling warmth from the sun on your skin, even when you are not in direct contact with it.

How does the Gulf Stream demonstrate convection?

Back

The Gulf Stream demonstrates convection by moving warm water from the equator towards the poles, creating a current that affects climate.
