Question:easy
A thermodynamic system is compressed adiabatically, then its temperature
A thermodynamic system is compressed adiabatically, then its temperature
Show Hint
In a cycle the internal energy returns to its initial value, so work equals net heat.
Updated On: Oct 1, 2026
- becomes zero.
- remains constant.
- increases.
- decreases.
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Energy accounting:
After one cycle the system has the same energy as before. Any heat that went in and did not stay stored must have turned into work.
Step 2: Result:
Net work = net heat absorbed (B).
Final Answer:
Option (B). \[ \boxed{\text{(B)}} \]
