Thermodynamics Question 114
Question: A system performs work $ \Delta W $ when an amount of heat is$ \Delta Q $ added to the system, the corresponding change in the internal energy is $ \Delta U $ . A unique function of the initial and final states (irrespective of the mode of change) is
[CPMT 1981; J & KCET 2004]
Options:
A) $ \Delta Q $
B) $ \Delta W $
C) $ \Delta U $ and $ \Delta Q $
D) $ \Delta U $
Show Answer
Answer:
Correct Answer: D
Solution:
Change in internal energy (DU) depends upon initial an find state of the function while DQ and DW are path dependent also.
