### Carnot Engine Efficiency and Performance Analysis A Carnot engine operates between two heat reservoirs at temperatures \( T_H = 322 \, K \) and \( T_C = 65 \, K \). #### 1) (a) What is its efficiency? **Answer Box:** \[ \% \quad \text{Submit} \] *You currently have 0 submissions for this question. Only 10 submissions are allowed. You can make 10 more submissions for this question.* --- #### 2) (b) If it absorbs 118 J from the hot reservoir during each cycle, how much work does it do? **Answer Box:** \[ \text{J} \quad \text{Submit} \] *You currently have 0 submissions for this question. Only 10 submissions are allowed. You can make 10 more submissions for this question.* --- #### 3) (c) How much heat does it give off in each cycle? **Answer Box:** \[ \text{J} \quad \text{Submit} \] *You currently have 0 submissions for this question. Only 10 submissions are allowed. You can make 10 more submissions for this question.* --- #### 4) (d) What is the coefficient of performance of this engine when it works as a refrigerator between these two reservoirs? **Answer Box:** \[ \text{Submit} \] *You currently have 0 submissions for this question. Only 10 submissions are allowed. You can make 10 more submissions for this question.* --- ### Explanation **Carnot Engine Efficiency Calculation:** The efficiency (\( \eta \)) of a Carnot engine is determined by the temperatures of the hot (\( T_H \)) and cold (\( T_C \)) reservoirs: \[ \eta = 1 - \frac{T_C}{T_H} \] Where \( T_H \) and \( T_C \) are the absolute temperatures of the hot and cold reservoirs, respectively. **Work and Heat Transfer:** 1. **Work Done (\( W \))**: \[ W = Q_H \cdot \eta \] 2. **Heat Rejected (\( Q_C \))**: \[ Q_C = Q_H - W \] **Coefficient of Performance (COP) for Refrigerators:** The coefficient of performance for a refrigerator (\( \text{
