A Carnot engine whose high-temperature reservoir is at 483 K has an efficiency of 40%. By how much should the temperature of the low-temperature reservoir be decreased to increase the efficiency to 50%?

Explanation

To solve the problem, we will use the formula for the efficiency of a Carnot engine, which is given by:

\[ \eta = 1 - \frac{T_2}{T_1} \]

where:
- \(\eta\) is the efficiency,
...
