Question 1

An ideal gas at 300 K and 150 kPa occupies 2 m³. If pressure is increased isothermally to 300 kPa, what is the final volume?

0.5 m³ 1.0 m³ 1.5 m³ 4.0 m³

Correct Answer:

1.0 m³

Question 2

For a closed system, the first law of thermodynamics with heat in positive and work out positive is:

ΔU = Q − W ΔU = Q + W for all processes Q = W for any isothermal process ΔH = 0 for all adiabatic processes

Correct Answer:

ΔU = Q − W

Question 3

A Carnot engine operates between 600 K (hot) and 300 K (cold). What is the maximum thermal efficiency?

25% 50% 75% 100%

Correct Answer:

50%

Question 4

Steam at 1 MPa with quality x = 0.90. To find specific enthalpy h, you need from steam tables at 1 MPa:

h_f and h_g (saturated liquid and vapor enthalpies) Superheated table only Compressed liquid table only Ideal gas cpT alone

Correct Answer:

h_f and h_g (saturated liquid and vapor enthalpies)

Question 5

During an isobaric heating of an ideal gas, 500 kJ of heat is added and 200 kJ of boundary work is done by the gas. The change in internal energy is:

200 kJ 300 kJ 500 kJ 700 kJ

Correct Answer:

300 kJ
