Conduction, Convection, Radiation Worksheet

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one through physical touch.

Front

What is convection?

Back

Convection is the transfer of heat through liquids or gases caused by the movement of the fluid itself. Warmer, less dense fluid rises while cooler, denser fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through empty space.

Front

Example of conduction in everyday life?

Back

Cooking food using a pan on a stove is an example of conduction, where heat is transferred from the stove to the pan and then to the food.

Front

Example of convection in everyday life?

Back

Boiling water is an example of convection, where hot water rises to the top and cooler water sinks, creating a circular motion.

Front

Example of radiation in everyday life?

Back

Feeling heat from sitting next to a space heater is an example of radiation, where heat is transferred through infrared waves.

Front

What happens to particles during conduction?

Back

In conduction, particles in the hotter object vibrate faster and transfer their energy to adjacent, cooler particles.

Front

What happens to particles during convection?

Back

In convection, warmer particles move up while cooler particles move down, creating a cycle that transfers heat throughout the fluid.

Front

What happens to particles during radiation?

Back

In radiation, heat is transferred through electromagnetic waves, and particles do not need to be in contact or even in the same medium.

Front

What is the primary medium for conduction?

Back

The primary medium for conduction is solids, as particles are closely packed and can easily transfer energy.
