Inside a heated vacuum chamber is a surface having an area of (A) 0.5 m² at a temperature of (T) 150°C and an emissivity of (ε) 0.7. The walls of the vacuum chamber are at (T_w) 25°C. Determine (a) the radiation emitted by the surface, and (b) the net radiation exchanged between the surface and the known schematic.
