Aglass bulb with radius r = 15 cm is filled with water vapor at a temperature of t = 500 k. on the exterior of the bulb a spot with area a = 2.0 mm2 is placed in contact with liquid nitrogen. this causes the temperature of the spot to drop well below 0â—¦c. when the gaseous water molecules strike this area from inside they immediately freeze effectively removing them from the gas. determine how much time it takes for the pressure in the bulb to reduce to half its original value. assume the temperature of the gas in the container remains at 500 k

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
