Answer 2

Calculation of the Temperature of the Heater

To determine the temperature of the heater in a thermal machine with a maximum efficiency of 35% and a refrigerator temperature of 585K, we can use the Carnot efficiency formula. The Carnot efficiency is given by the equation:

Efficiency = 1 - (Tc/Th)

where: - Efficiency is the maximum efficiency of the thermal machine (35% or 0.35) - Tc is the temperature of the cold reservoir (585K) - Th is the temperature of the hot reservoir (unknown)

We can rearrange the equation to solve for Th:

Th = Tc / (1 - Efficiency)

Substituting the given values, we have:

Th = 585K / (1 - 0.35)

Calculating this, we find:

Th ≈ 900K

Therefore, the temperature of the heater in the thermal machine is approximately 900K.

Please note that this calculation assumes ideal conditions and does not take into account any real-world factors that may affect the efficiency of the thermal machine.
