Question

Identify the incorrect statement related to a cyclic process

Answer 1

Answer:

Answer

Given: Cyclic process

Solution:

1. Cyclic process is a process where the initial and the final conditions coincides as the process forms a closed loop.

2. For a cyclic process, △U=0, so Q=W from first law of thermodynamics.

3. Work done is given by area of the loop that is formed. If the direction of loop is clockwise then work done by system is positive and if the direction of loop is anticlockwise then work done by system is negative.

Hence the correct option is C.

option C is w 0

Answer 2

Option (C) that is = W>0 is the right choice

Explanation:

Given: Cyclic Process

1. A cyclic process is a process where the initial and final conditions coincide because the process forms a closed loop.

2. For a cyclic process, U=0, so Q=W By the first law of thermodynamics.

3. The work done is given by the area of the loop to be formed. If the direction of the loop is clockwise then the work done by the system is positive and if the direction of the loop is counterclockwise then the work done by the system is negative.

Thus, the correct choice is C.
