### Carnot Engine Thermodynamics

1. A Carnot engine operates between reservoirs at 610 K and 315 K. If the engine absorbs 75 J per cycle at the hot reservoir.

Calculate:

(a) **The efficiency, \( e \), of the engine:**

\[ e = \ \] [Input Box]

(b) **The work output per cycle:**

\[ W_{\text{per cycle}} = \ \] [Input Box] J

---

The image provided shows a problem related to a Carnot engine, a theoretical thermodynamic cycle proposed by Nicolas Léonard Sadi Carnot. According to Carnot's theorem, no engine operating between two heat reservoirs can be more efficient than a Carnot engine operating between the same reservoirs.

- **Efficiency (\( e \)):** The efficiency of a Carnot engine is determined by the temperatures of the hot (\( T_H \)) and cold (\( T_C \)) reservoirs. It is given by the formula:
  \[
  e = 1 - \frac{T_C}{T_H}
  \]
  where \( T_H \) is the absolute temperature of the hot reservoir, and \( T_C \) is the absolute temperature of the cold reservoir.

- **Work output per cycle:** The work output (\( W_{\text{per cycle}} \)) is related to the engine efficiency and the heat absorbed from the hot reservoir (\( Q_H \)). It can be calculated using:
  \[
  W_{\text{per cycle}} = e \times Q_H
  \]
  where \( Q_H \) is the heat absorbed per cycle at the hot reservoir.

Here, the temperatures and the heat absorbed are provided:

- \( T_H = 610 \) K
- \( T_C = 315 \) K
- \( Q_H = 75 \) J

You can calculate the values by plugging in the numbers into the formulas provided.

This exercise helps understand the fundamental principles of thermodynamics and the efficiency limits of heat engines.
