Answer 2

Given:

The initial temperature of the gas = 127°C= 400 K

The initial pressure of the gas = 2 atm

The initial volume of the gas = 2 L

Final temperature of the gas = 927°C= 1200K

To find:

The new pressure of the gas if volume remains constant.

Solution:

We know that:

PV=nRT

If all the terms are constants except pressure and volume then pressure is directly proportional to temperature and:

P1/T1 = P2/T2

Substituting the values we get:

2/400 = P2/1200

P2= 2×1200/400

P2 = 6 atm

Thus, the new pressure of the gas is 6 atm.
