Given that,

Atmospheric Pressure = 14.7 psi

Cooking Pressure = 14.7 + 11.1 = 25.8 psi

Take, Atmospheric Temperature = 25 °C

Cooking Temperature = ?

Since, we know that Gas equation is given by:

PV = nRT

or

P ∝ T

P1 / T1 = P2 / T2

14.7 / 25 = 25.8 / T2

T2 = 25*25.8/14.7

T2 = 43.87 °C

The cooking pressure will be 43.87 °C.
