A10,000 m^3 room has a valve leaking tetrachloroethylene, which is adding 50 mg/min of vapor to the room air. the gev system moves 75 m^3/min of air through the room.
a) what will be the cmax of tetrachloroethylene vapor in the air?
b) if the leak stops after reaching the maximum concentration what will be the vapor concentration in 1 hour?
assume the blower speed of gev in increased to 100 m^3/min.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

An inventor claims to have developed a reversed heat engine (ie. a heat pump) which is able to deliver 10 kj heat into the room at 20°c from outside ambient temperature of -10°c by consuming only 2 kj electricity in winter. this claim is a)-impossible b)-possible only if the heat pump is ideal c)-practically possible d)-unable to be assessed as it depends on the working fluid used in the heat pump.
