Multiply P1 by 1.155

Explanation:

Temperature and pressure are directly proportional. This means that an increase in pressure would lead to an increase in temperature.

Mathematically, P1T1 = P2T2

All we need to do is make P2 the subject of the relation.

As we can see from the question, T1 = 50 = 273 + 50 = 323K

T2 = 100 = 273 + 100 = 373K

P2 = P1T1/T2

P2 = P1 * 373/323

P2 = 1.155P1

Hence, the factor is that we multiply the P1 by 1.155
