What is conduction?

Back

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

What is convection?

Back

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

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur in a vacuum, such as space.

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 pot of boiling water.

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation pattern.

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin, even though the air around you may be cool.

Front

What role does density play in convection?

Back

In convection, warmer fluids become less dense and rise, while cooler fluids become more dense and sink, creating a circulation pattern.

Front

How does conduction occur in solids?

Back

In solids, conduction occurs as vibrating particles transfer kinetic energy to neighboring particles through direct contact.

What is the primary difference between conduction and convection?

Back

The primary difference is that conduction occurs in solids through direct contact, while convection occurs in fluids through the movement of the fluid itself.

Front

Can convection occur in solids?

Back

No, convection cannot occur in solids because the particles in solids do not move freely; convection requires the movement of fluids.
