The temperature of a gas increased from 398k to 455k inside of a rigid container. if the original pressure of the gas was 1.22atm, what will the pressure of the gas after the temperature change?

According to pressure law, at a constant volume, the pressure of a given mass of gas is directly proportional to its temperature in Kelvin scale.

Here, P1 = Initial pressure of the gas = 1.22 atm

T1 = Initial temperature of the gas = 398 K

T2 = Final temperature of the gas = 455 K

P2 = Final pressure of the gas = ?

Therefore,

Therefore, the required pressure of the gas after the change in temperature is 1.4 atm.

the answer is c i took the test
