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
