The 8-mm-thick bottom of a 220-mm-diameter pan may be made from aluminum (k = 240 w/m ⋅ k) or copper (k = 390 w/m ⋅ k). when used to boil water, the surface of the bottom exposed to the water is nominally at 110°c. if heat is transferred from the stove to the pan at a rate of 600 w, what is the temperature of the surface in contact with the stove for each of the two materials?

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
