🤓 Based on our data, we think this question is relevant for Professor Dixon's class at UCF.

FREE Expert Solution

We are asked to calculate the vapor pressure of water inside the pressure cooker.

For this problem, we can use the Clausius-Clapeyron Equation:


lnP2P1 = -HvapR[1T2-1T1]


where:

P1 = vapor pressure at T1

P2 = vapor pressure at T2

ΔHvap = heat of vaporization (in J/mol)

R = gas constant (8.314 J/mol•K)

T1 and T2 = temperature (in K).
