The amount of heat required to raise the temperature of one gram of a substance by 1°C.

The change in length of a material per degree Celsius change in temperature.

The ability of a material to transfer heat from one end to the other.

Metals are examples of good heat conductors.

The rate at which a body with uneven temperature reaches equilibrium.

At 0°C, atoms lose their vibrational ability.

α = (Final Length – Initial Length) / Initial Length x (Final Temperature – Initial Temperature).

Materials like plastics and ceramics are thermal insulators.

The temperature at which atomic vibration stops (-273°C).

Thermal conductivity is directly related to the number of free electrons in a material.
