Question

under what temperature will volume of gas at 0 degree celcius double itself if the pressire is kept constant ????​

Answer 1

273.15° C

Explanation: Ideal gasses tend to double in volume when their temperature doubles. 0°C = 273.15K so double 273.15 gives 546.3K.

Converting back to Celcius

546.3-273.15 =273.15°C
