Pressure cookers allow food to cook faster because the higher pressure inside the pressure cooker increases the boiling temperature of water. a particular pressure cooker has a safety valve that is set to vent steam if the pressure exceeds 3.4 atm. what is the approximate maximum temperature

Explanation:

The question is asking, "At what temperature does the vapour pressure of water equal 3.4 atm?"

To answer this question, we can use the Clausius-Clapeyron equation:

Data:

p₁ = 1 atm;    T₁ = 373.15C

p₂ = 3.4atm; T₂ = ?

R  = 8.314 J·K⁻¹mol⁻¹

(The enthalpy of vaporization changes with temperature. Your value may differ from the one I chose.)
