Which material is the best conductor of electricity?

Back

Copper is the best conductor of electricity among common materials.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation. It does not require a medium to travel.

Front

How does heat transfer occur when touching a cold window?

Back

Heat is moving from the hand to the window, making the hand feel cold.

Front

What happens to molecules during the phase change from liquid to gas?

Back

The average distance between molecules increases as they gain energy and move apart.

Front

What type of heat transfer occurs when a pan is placed on a hot stove?

Back

Conduction occurs as heat is transferred from the stove to the pan through direct contact.

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 radiation in everyday life?

Back

An example of radiation is feeling warmth from the sun on your skin, even when you are not in direct contact with it.
