Task 50402.
A copper ball with a diameter of d = 10 cm with a completely black surface cools while in a thermostat, the walls of which (also absolutely black) are maintained at a temperature close to absolute zero. Determine to what temperature the ball will cool down after a period of 5 hours if its initial temperature is T0 = 300 K. The specific heat of copper is Sud = 0.38 J / (g * K), the density of copper is 8.93 g / cm3.
