An older home is built in an area with a high radon flux (9.5 pCi m-2 s-1). The basement slab does not have a plastic vapor barrier so 90% of the radon flux passes into home. The house floor area is 2500 ft2 (232 m2), house volume is 20,000 ft3 (566 m3) and the air exchange rate is 1.5 ach. Neglect decay and ambient radon. Find the indoor steady-state radon concentration.

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
