The lowest hypothetical or imaginary temperature at which gases are supposed to occupy zero volume is called absolute zero.

T (K) = t (C) + 273.15 O K = - 273.15° C + 273.15

⟹

Volume of gas at

- 273.15° C

becomes zero. i.e. gas doesn't exist at this temperature. (at zero kelvin, the motion of fluids is also zero, ACC to brownian)
