Question:easy
In a cyclic process, work done by the system is
In a cyclic process, work done by the system is
Show Hint
In a cycle the internal energy change is zero, so W = Q.
Updated On: Oct 1, 2026
- zero.
- equal to the heat given to system.
- more than the heat given to system.
- independent of heat given to system.
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Cycle
Start and end states are the same, so $\Delta U = 0$.
Step 2: First law
$Q = \Delta U + W$ reduces to $Q = W$.
Step 3: Answer
Option (B).
Final Answer:
Option (B). \[ \boxed{W = Q} \]
Start and end states are the same, so $\Delta U = 0$.
Step 2: First law
$Q = \Delta U + W$ reduces to $Q = W$.
Step 3: Answer
Option (B).
Final Answer:
Option (B). \[ \boxed{W = Q} \]
