2. For a steady state system, 10 J of heat is supplied to the system, what is the work done by the system?
a) 10 J
b) 20 J
c) 30 J
d) 40 J
View Answer

Answer: a
Explanation: Change in the internal energy for a steady-state system is always zero so Q = W.

a) + x J
b) –x J
c) 0 J
d) None of the mentioned
View Answer

Answer: b
Explanation: Change in the internal energy for a steady-state system is always zero so Q + W= 0.

4. 10 J of heat is removed from a steady state system, what is the work done on the system?
a) – 10 J
b) 10 J
c) – 5 J
d) 5 J
View Answer

Answer: b
Explanation: 0 = – 10 + W.

5. 25 J of work is done by a steady state system, what is the heat supplied to the system?
a) – 25 J
b) 25 J
c) 20 J
d) – 20 J
View Answer

Answer: b
Explanation: 0 = – 15 + Q.

6. 20 J of heat is supplied to a system and a work of 30 J performed on it. If 50 J of heat is removed from the system, which type of system is it?
a) Steady state
b) Unsteady state
c) Closed
d) None of the mentioned
View Answer

Answer: a
Explanation: ∆E = 0.

7. 10 J of heat is supplied to a system and a work of 30 J performed on it. If 50 J of heat is removed from the system, which type of system is it?

View Answer

Answer: b
Explanation: ∆E is not equal to zero.

9. If 25 J is work is done by a system and same amount of heat is also supplied to the system. What kind of system is it?
a) Steady state
b) Unsteady state
c) Closed
d) None of the mentioned
View Answer

Answer: a
Explanation: ∆E is equal to zero.

10. There must be no accumulation of mass or energy over the time period of interest in a _________
a) Steady state
b) Unsteady state
c) Closed
d) None of the mentioned
View Answer

Answer: a
Explanation: There must be no accumulation of mass or energy over the time period of interest in a Steady state.
