Water is to be heated from room temperature (t = 10 °c) to boiling (t = 1 10 c) for a temperature rise of δt=100 °c. give the initial temperature, ti , final temperature, t, and temperature rise, δt in degrees kelvin (k)

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
