Question

Теплова машина передає холодильнику 3/4 теплоти, отриманої від нагрівача. Вважаючи, що теплова машина працює за циклом Карно, знайдіть температуру холодильника. Температура нагрівача 600К

Answer 1

Qx/Qн = Tx/Tн
Tx = Tн · Qx/Qн
Tx = 600·3/4 = 450 К

Answer 2

Calculating the Temperature of the Refrigerator in a Carnot Cycle

To calculate the temperature of the refrigerator in a Carnot cycle, we can use the Carnot efficiency formula:

Carnot efficiency (η) = 1 - (Tc/Th)

Where: - Tc = temperature of the cold reservoir (refrigerator) - Th = temperature of the hot reservoir (heater)

Given: - Temperature of the heater (nagrivach) = 600K - The heat engine transfers 3/4 of the heat received from the heater to the refrigerator

We can use the Carnot efficiency formula to find the temperature of the refrigerator.

Calculations

First, let's calculate the Carnot efficiency using the given information.

Carnot efficiency (η) = 1 - (Tc/Th)

Given Th = 600K, and the efficiency is 3/4, we can solve for Tc.

3/4 = 1 - (Tc/600)

Now, let's solve for Tc:

1/4 = Tc/600

Tc = 600 * (1/4)

Tc = 150K

So, the temperature of the refrigerator (holodilnyk) in the Carnot cycle is 150K.
