Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat from one object to another through direct contact.

Front

What is convection?

Back

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

How does warm air behave in convection?

Back

Warm air rises because it is less dense than cool air, which sinks.

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through empty space without the need for a medium.

What is an example of conduction in everyday life?

Back

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

Front

What role does density play in convection?

Back

In convection, less dense (warmer) fluids rise while denser (cooler) fluids sink, creating a current.

Front

What is a real-world example of convection?

Back

A real-world example of convection is the heating of water in a pot on a stove.

Front

How does radiation differ from conduction and convection?

Back

Radiation does not require a medium to transfer heat, while conduction and convection do.

Front

What is the significance of thermal conductivity in conduction?

Back

Thermal conductivity is a measure of how well a material conducts heat; higher conductivity means better heat transfer.
