Temperature

A measure of the average kinetic energy of particles in a substance.

Thermal Equilibrium

When all objects in a system are at the same temperature.

Thermogram

Visual representation of heat patterns on a surface.

Gas

State of matter that holds the most energy.

Potential Energy

Energy an object has due to its position.

Kinetic Energy

Energy of motion.

Open System

Can exchange energy with the environment.

Closed System

Can only exchange energy without matter exchange.

Geothermal

Energy transferred between a house and the ground.

Radiation

Transfer of thermal energy by electromagnetic waves.

Thermal Energy

Sum of kinetic and potential energy in particles.

Convection

Circulation of particles within a material caused by differences in thermal energy and density.

System

Collection of objects that interact in some way.

Heat

Movement of thermal energy from a warmer object to a colder object.

Conduction

Transfer of thermal energy between two objects that are touching.
