What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when faster-moving particles collide with slower-moving ones, transferring energy.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks, creating a circulation pattern.

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.

Which color of visible light has the shortest wavelength?

Back

Violet has the shortest wavelength among the colors of visible light.

How does heat flow when ice melts in water?

Back

Heat flows from the water to the icecap, causing the ice to melt.

What happens to the handle of a metal spoon in hot soup?

Back

The handle warms up due to conduction, as heat is transferred from the hot soup to the spoon.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is how heat lamps keep baby chickens warm by emitting infrared radiation.

Front

What is the role of convection in weather patterns?

Back

Convection plays a crucial role in weather patterns by causing warm air to rise and cool air to sink, leading to wind and cloud formation.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot bowl of soup.
