1.The interaction that occurs between a system and its surroundings as the system executes a process, which is the result of the system being at a temperature different from that of the surroundings, is:
(a)mass transfer
(b)heat transfer
(c)work transfer
(d)none of these
2.In order for a system to be in thermal equilibrium, which of the folllowing properties must be the same throughout the system?
(a)mass
(b)pressure
(c)temperature
(d)volume
3.An insulated piston-cylinder device initially contains 0.01m^3 of steam at 200 degrees C. The force on the piston is such that it maintains a constant pressure of 400 kPa inside. A valve is now opened nad steam at 1 MPa, 200 degrees C is allowed to enter the cylinder until the volume inside increases to 0.04 m^3. Determine
(a) the final temperature of the steam and
(b) the amount of mass transwer
4.When a gas is to be stored, the type of compression that would be optimal is
(a) isothermal
(b) adiabatic
(c) polytropic
(d) constant volume
(e) none of the above
