Heat and Energy test review

Front

What is a conductor?

Back

A material that allows heat or electricity to flow through it easily. Examples include metals like steel, silver, and aluminum.

Front

What is radiation in the context of heat transfer?

Back

A method of heat transfer that occurs through electromagnetic waves, such as sunlight warming the Earth.

Front

What type of energy is associated with motion?

Back

Kinetic energy, which is the energy an object has due to its motion.

Front

Which states of matter have a definite volume?

Back

Solids and liquids have a definite volume, while gases do not.

Front

What is potential energy?

Back

The type of energy that is stored in an object due to its position or state, such as a rock at the top of a hill.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position.

Front

What is convection?

Back

A method of heat transfer that occurs in fluids (liquids and gases) where warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is conduction?

Back

A method of heat transfer that occurs through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is the role of the sun in heat transfer?

Back

The sun transfers heat to the Earth primarily through radiation.

Front

What is an example of a good conductor of heat?

Back

Metals like silver, copper, and aluminum are good conductors of heat.
