Options

A. Reversible process
B. Cyclic process
C. Cyclic reversible process
D. Isochoric process

Answer

To determine the type of process described in the question, let's analyze the changes step by step.

### Step 1: Identify the Initial and Final States
The system starts at state X with conditions \( P_1, V_1, T_1 \). It then undergoes a series of changes to reach back to state X.

### Step 2: Analyze Each Transition
1. **From X to W**: The system transitions from \( P_1, V_1, T_1 \) to \( P_2, V_2, T_1 \). Here, the pressure changes from \( P_1 \) to \( P_2 \) while the temperature remains constant at \( T_1 \).

2. **From W to Z**: The system then transitions from \( P_2, V_2, T_1 \) to \( P_3, V_2, T_2 \). In this step, the pressure changes from \( P_2 \) to \( P_3 \) and the temperature changes from \( T_1 \) to \( T_2 \) while the volume remains constant at \( V_2 \).

3. **From Z back to X**: Finally, the system returns from \( P_3, V_2, T_2 \) back to \( P_1, V_1, T_1 \). This means that the system undergoes changes in pressure, volume, and temperature to return to its original state.

### Step 3: Determine the Type of Process
Since the system returns to its original state after undergoing a series of changes, this process is classified as a **cyclic process**. In a cyclic process, the initial and final states are the same, regardless of the path taken to get there.

### Conclusion
The overall process described in the question is a **cyclic process**.
