Absolute zero temperature and the absolute zero scale

The absolute zero temperature of - 273 °C is the lowest possible temperature that could be attained.

The volume of the gas becomes zero at the absolute zero temperature but before this temperature is attained, all of the gas would have changed to liquid.

The Kelvin Scale is also known as the absolute zero temperature scale.

The SI Unit is Kelvin (K)

The temperature interval is 1K = 1 °C .

By referring the Celsius scale, we have the Kelvin scale, T = (θ + 273) K

With T being the temperature at the Kelvin θ being the temperature at the Celsius scale.
