Answer 2

To increase the maximum efficiency of a heat engine;

• Increase the temperature of the hot reserve
• Decrease the temperature of the cold reserve

The Carnot efficiency of a heat engine is calculated as follows;

$Eff = \frac{T_H - T_c}{T_H} \times 100\%$

where;

• $T_H$ is the temperature of the hot reserve
• $T_C$ is the temperature of the cold reserve

Thus, to increase the maximum efficiency of a heat engine;

• Increase the temperature of the hot reserve
• Decrease the temperature of the cold reserve
