Thermodynamics Question 46
Question: We consider a thermodynamic system. If $ \Delta U $ represents the increase in its internal energy and W the work done by the system, which of the following statements is true
[CBSE PMT 1998]
Options:
A) Adiabatic expansion
B) Adiabatic compression
C) Isothermal expansion
D) Isothermal compression
Show Answer
Answer:
Correct Answer: B
Solution:
In adiabatic process DU = -DW. In compression DW is negative, so DU is positive i.e. internal energy increases.
