Front

temperature

Back

A measure of the average kinetic energy of an object's particles.

Front

thermal energy

Back

Sum of the kinetic energies of all the particles that make up an object.

Front

thermal expansion

Back

Tendency of particles to spread out when the kinetic energy increases.

Front

conduction

Back

Transfer of thermal energy by direct contact of two objects or portions of matter.

Front

thermal conductor

Back

Substances that thermal energy can easily move through.

Front

thermal insulator

Back

substances that thermal energy cannot move through

Front

convection

Back

a type of thermal energy transfer in which currents carry thermal energy from one part of the fluid to another

Front

radiation

Back

the process of thermal energy transfer by electromagnetic waves

Front

hypothermia

Back

condition caused by the loss of too much body heat

Front

thermal equilibrium

Back

state in which all parts of a system are at the same temperature
