Question

Water is completely filling black metallic vessel having cubic form and thin walls. The mass of water is 1 kg and initial temperature 50 C. This cubic vessel is placed into black cavity whose walls are kept at the constant temperature of 0 C. Find time t it takes for the water to cool down to 10 C. Water specific heat is 4200 (J/kg K-1 .) After you find an answer, estimate whether this radiation mechanism would be responsible for the real-life water cooling and what other mechanisms might be in play.
