The temperature of a gas sample is increased from 50 degrees celsius to 100 degrees celsius. By what factor must the pressure be changed if the volume is kept constant?

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

For temperatures to be increased in gas there would have to be heat
