24-25 Energy Study Guide

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, and does not require a medium.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as gravitational potential energy in a raised object.

Front

How does temperature affect heat transfer?

Back

Heat transfer occurs from areas of higher temperature to areas of lower temperature until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of chemical energy being converted to heat energy?

Back

An example is burning wood in a fire, where the chemical energy stored in the wood is converted into heat and light.

Front

What is the role of a conductor in heat transfer?

Back

A conductor is a material that allows heat to pass through it easily, such as metals like copper and aluminum.
