Convection, Conduction, Radiation

Front

What is the original source of most of the energy on the surface of the Earth?

Back

Energy that reaches Earth by radiation from the sun.

Front

What happens to an egg placed on hot black pavement?

Back

The pavement will conduct the heat and cook the egg.

Front

What is the definition of CONDUCTION?

Back

When heat transfers from objects that are touching.

Front

What can happen as a result of radiation?

Back

A car’s inside temperature rises to over 100 degrees on a sunny day.

Front

What is the definition of CONVECTION?

Back

When heat is transferred by movement of gas or liquids. It is also when gas/liquid becomes less dense and rises or becomes more dense and sinks.

Front

What is the process of heat transfer through direct contact called?

Back

Conduction.

Front

What is an example of convection in everyday life?

Back

Boiling water where hot water rises and cooler water sinks.

Front

How does radiation transfer heat?

Back

Through electromagnetic waves, such as sunlight.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a hot soup.

Front

What is the main difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.
