Radiation, convection, conduction

Front

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.

How does conduction occur in solids?

Back

In solids, conduction occurs as particles vibrate and collide with neighboring particles, transferring energy.

Front

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 an example of convection in everyday life?

Back

An example of convection is the heating of water in a pot, where hot water rises and cooler water sinks, creating a circulation pattern.

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, which can occur in a vacuum and does not require a medium.

How does the sun heat the Earth?

Back

The sun heats the Earth primarily through radiation, as sunlight travels through space and warms the planet's surface.

What is the primary method of heat transfer in liquids?

Back

The primary method of heat transfer in liquids is convection.

Front

What happens to the density of a fluid when it is heated?

Back

When a fluid is heated, its density decreases, causing it to rise in a convection current.

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove, where heat transfers from the stove to your hand.

Front

What is the role of thermal conductivity in conduction?

Back

Thermal conductivity is a measure of a material's ability to conduct heat; materials with high thermal conductivity transfer heat more efficiently.
