TE_ Vocab/Concepts Flashcard "F" (Final)

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, creating a circulation pattern.

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, such as when a metal spoon gets hot in soup.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. It does not require a medium to travel through, allowing heat from the sun to reach the Earth.

Front

What direction does heat travel?

Back

Heat always travels from warm to cool areas.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

Front

What happens to molecules when heat is added?

Back

When heat is added to molecules, they gain energy and move faster, causing the substance to increase in temperature.

Front

What is the difference between heat and temperature?

Back

Heat is the total energy of molecular motion in a substance, while temperature is a measure of the average energy of molecular motion.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of radiation in everyday life?

Back

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