The gas is cooled and loses 65 J of heat. The gas contracts as it cools and work done on the system equal to 20 J is exchanged with the surroundings. What are q, w and `DeltaE` ?

Explanation

To solve the problem, we need to determine the values of \( q \), \( w \), and \( \Delta E \) based on the information provided.

### Step-by-Step Solution:

1. **Identify the Heat Transfer (\( q \))**:
- The gas loses 65 J of heat. Since heat is released from the system, we take this value as negative.
- Therefore, \( q = -65 \, \text{J} \).
