    1.155 times

    Explanation:

    The temperature of gas is directly proportional to the pressure of the gas given that the volume is kept constant (P∝T). However, it should be kept in mind that the temperature is measured in Kelvin.

    The initial temperature of the gas is 50 + 273.15 = 323.15 Kelvin.

    The final temperature of the gas is 100 + 273.15 = 373.13 Kelvin.

    The final temperature is (373.15/323.15) times the initial temperature i. e 1.155
