### 1. An ideal gas expands isothermally along AB and does 720 J of work (see below).

#### Diagram Explanation:
- A Pressure-Volume (p-V) diagram is shown with an ideal gas undergoing different processes.
- The diagram depicts three distinct points: A, B, and C, forming a closed cycle.
- The path from A to B is marked with an arrow indicating an isothermal expansion.
- The path from B to C suggests an adiabatic expansion.
- The path from C to A is a different thermodynamic process closing the cycle.

**Questions:**

**(a) How much heat does the gas exchange along AB? Is the heat absorbed by the gas or released to the surroundings?**

\[ Q_{AB} = \_\_\_\_ \ (J) \]

---

**(b) The gas then expands adiabatically along BC and does 430 J of work. When the gas returns to A along CA, it exhausts 100 J of heat to its surroundings. How much work is done on the gas along the path CA?**

\[ \text{Work done on gas from C to A} = \_\_\_\_ \ (J) \]

---

**(c) If the cycle below is used as a heat engine, calculate the efficiency of the cycle.**

\[ e = \_\_\_\_ \]

---

_Note: Consider the relationships for different thermodynamic processes to calculate the required values. For an isothermal process, the heat absorbed by the gas is equal to the work done (Q = W). For the adiabatic process, no heat is exchanged (Q = 0). The net work done in the cycle can be used to find efficiency._
