Note I only have 15 mintues

Which of the following is not consistent with the Clausius Inequality:

2.

During a constant temperature process, 150 kJ of heat is added to a system at 100 K. How much does the entropy of the system change due to the added heat?

Which of the following is not consistent with the Clausius Inequality:

A) The Cyclic Integral of Heat over Temperature (Q/T) is equal to zero for reversible processes.
B) The Cyclic Integral of Heat over Temperature (Q/T) is less than zero for irreversible processes.
C) Cyclic Integral of Heat over Temperature (Q/T) is greater than zero for irreversible processes.

2.

During a constant temperature process, 150 kJ of heat is added to a system at 100 K. How much does the entropy of the system change due to the added heat?

A) 150 kJ/K
B) 1.5 kJ/K
C) 0.666 kJ/K
D) 0.15 kJ/K

Explanation / Answer

1) C) Cyclic Integral of Heat over Temperature (Q/T) is greater than zero for irreversible processes.

2) dS=dQ/T =150*1000/100 = 1.5kJ/k

B is the correct answer
