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 312 degrees, 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 refrigerator (312 degrees) - Th is the temperature of the heater (unknown)

To solve for Th, we rearrange the equation:

Th = Tc / (1 - Efficiency)

Substituting the given values:

Th = 312 / (1 - 0.35)

Now we can calculate the temperature of the heater.

Th = 312 / 0.65 Th ≈ 480 degrees

Therefore, the temperature of the heater is approximately 480 degrees.

Please note that the calculation assumes an ideal Carnot cycle and does not take into account any real-world losses or inefficiencies.
