Heat Transfer

Front

What are the three main types of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction in the context of heat transfer.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat between liquids or gases due to the movement of the fluid.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves or packets of energy.

Front

How does convection occur in a liquid?

Back

Convection occurs when warmer, less dense parts of the liquid rise and cooler, denser parts sink, creating a circulation pattern.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection in cooking?

Back

An example of convection in cooking is using a convection oven, where hot air circulates to cook food evenly.

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 role does temperature play in heat transfer?

Back

Heat transfer occurs from areas of higher temperature to areas of lower temperature.

Front

What is the significance of thermal conductivity?

Back

Thermal conductivity is a measure of a material's ability to conduct heat; higher values indicate better heat conduction.
