You are absolutely right! When we consider Charle’s law, we predict the volume to be zero at 0K i.e., absolute zero is the absolutely lowest temperature possible.

Pl. also note that while we plot or solve problems involving volume and temperature, we have to plug in values of T after converting into Kelvin scale or else T will take –ve values and volume also becomes –ve that cannot exist.(Tk = TC + 273.15)
