Question

3. At what temperature in degree centigrade will the
volume of a gas, which is originally at 0°C,
double itself, pressure remaining constant.
​

Answer 1

Explanation:

This point, with a temperature of –273.15 ˚C, is the theoretical point where the samples would have “zero volume”. This temperature, -273.15 ˚C, is called absolute zero. An even more intriguing thing is that the value of absolute zero is independent of the nature of the gas that is used.
