A rigid 5.50-L pressure cooker contains steam initially at 100.0∘C under a pressure of 1.00 atm.
Assume that the molar specific heat at constant volume V is 25.9 J/mol·K and the molar specific heat at constant pressure p is 34.3 J/mol·K and that these values remain constant. The mass of a water molecule is 2.99×10^-26 kg.
To what temperature f would you have to heat the steam so that its pressure was 1.69 atm?
How much heat would you need to add to the steam to raise its pressure to 1.69 atm?
Calculate the specific heat of steam in units of J/kg·K.
