24. Thermocouple iron - constantan, which is a constant α = 5,3 • 10-5 / K and a resistance R = 15 ohms, closed on the galvanometer. One junction of the thermocouple is in a vessel with melting ice and placed in a second medium, the temperature of which is not known. Define this temperature, if the current flowing through the galvanometer, I = 0,2 mA, and the internal resistance of the galvanometer r = 150 ohms.
