1.	A body A of mass 0.5kg and specific heat 0.85J g^(-1) K^(-1) is at a temperature of 60^(@)C. Another body B of mass 0.3kg and specific heat 0.9 J g^(-1) K^(-10 is at a temperature of 90^(@)C. When they are connected through a conducting rod, heat will flow from
Answer» A to B B to A heat can't flow first from A to B, then B to A Solution :Here, `m_(A) = 0.5 kg, s_(A) = 0.85J g^(-1) K^(1), T_(A) = 60^(@)C`, `m_(B) = 0.3kg, s_(B) = 0.9 J g^(-1) K^(-1) and T_(B) = 90^(@)C` Heat always flows from a body of heigher temperature to a body of LOWER temperature. Since the body B is at a higher temperature, therefore heat will flow from body B to A
