Cond, Conv, Rad

Front

What is Conduction?

Back

Conduction is the transfer of heat through a solid material without any movement of the material itself. It occurs when two objects at different temperatures are in direct contact.

Front

What is Convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself. Warmer parts of the fluid rise while cooler parts sink, creating a circulation pattern.

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 a vacuum.

Example of Conduction in everyday life?

Back

An example of conduction is when you touch a hot stove and feel the heat transfer to your hand.

Front

Example of Convection in everyday life?

Back

An example of convection is boiling water in a pot, where hot water rises to the top and cooler water moves down.

Front

Example of Radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin.

How does an iron smooth clothes?

Back

An iron smooths clothes by conduction, transferring heat directly from the iron to the fabric.

Front

How do eggs cook in a frying pan?

Back

Eggs cook in a frying pan through conduction, as the heat from the pan is transferred directly to the eggs.

Front

How do ice cubes keep lemonade cold?

Back

Ice cubes keep lemonade cold through conduction, absorbing heat from the lemonade.

Front

What happens to air in a heated room?

Back

In a heated room, warm air rises and cooler air sinks, creating convection currents.
