Unformatted text preview: mechanically isolated from its surroundings. c. The system is contained in a frictionless piston and cylinder exposed to an atmosphere at pressure P and thermally isolated from its surroundings. d. The system is contained in a frictionless piston and cylinder exposed to an atmosphere at pressure P and is in thermal contact with a thermostatic bath maintained at temperature T. e. The system consists of two tanks of gas connected by tubing. A valve between the two tanks is fully opened for a short time and then closed. 7. Problem 2.1 in textbook. As a result of a chemical spill, benzene is evaporating at the rate of 1 g/min into a room that is 6 m * 6 m * 3 m in size and has a ventilation rate of 10 m 3 /min. a. Compute the steady-state concentration of benzene in the room. b. Assuming the air in the room is initially free of benzene, compute the time necessary for benzene to reach 95 percent of the steady-state concentration....
