The body of mass m = 10 g, and the surface S = 200 cm ^ 2, having a temperature of T1 = 600 K, put into the vacuum. To determine to what temperature T2 cools down body 30 to when the surface absorptivity of the body is equal to 0.4, and c is the specific heat of 330 J / (kg * K). Radiant flux incident on the body as a result of the radiation surrounding objects neglected.
Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
