  When you write your beginning statement, you are actually restating the Law of Conservation of Energy.

  The statement made is
  Heat Lost = Heat gained. The energy clearly goes somewhere and the heat lost = heat gained shows where.

  suppose you have two glasses of water with equal amounts of water in them. Suppose the warm one is at a temperature of 50oC and the Cooler one is at a temperature of 4OoC. If you mix them, the final temperature is 45oC.

  What have we done? We transferred heat haven’t you? The cool water got warmer. It got heat added to it from …

  the hot water. The hot water lost heat, but to whom? It must have had heat transferred to the cooler water. So at least we have resolved thermal Energy Transfer.

  There is work being done in this transfer. That is the Law of conservation of Energy.
