According to Charle's law,the volume of a given mass of a gas at a constant pressure will vary linearly with absolute temperature.The gas expands uniformly with temperature.We can extrapolate the straight line & see the relationship between cooling the gas & the volume.On further extraponation we find that the temperature where a gas would have no volume would be -273 degrees celcius.This temperature is called the absolute zero of temperature.Since an ideal gas would occupy zero volume at absolute zero of temperature,it is often thought to be the lowest temperature possible.
