A Carnot engine has an efficiency of 15.0%. It operates between constant temperature reservoirs differing in temperature by 55.0°C What is the temperature of the lower-temperature reservoir?

Explanation

To solve the problem, we will use the formula for the efficiency of a Carnot engine and the relationship between the temperatures of the two reservoirs.

### Step-by-Step Solution:

1. **Understand the Efficiency Formula**:
The efficiency (η) of a Carnot engine is given by the formula:
\[
\eta = 1 - \frac{T_2}{T_1}
