Question

At what tempareture degree centigratede will the volume of a gas which is originally at 0° c double itself, pressure remain constant

Answer 1

At constant pressure P and fixed number of moles n, Volume V grows proportionally totemperature T. (R is a universal constant.) Thus, volume doubles when temperaturedoubles. At 0°C, the absolute temperature is T = 273.15 K. The double of that is 546.30 K = +273.15°C.
