Question
Which one of the following equation is correct*Heat given by hot water + heat taken by cold water = heat taken by calorimeterHeat given by hot water - heat taken by cold water = heat taken by calorimeterHeat taken by cold water = heat taken by calorimeter + Heat given by hot waterHeat taken by hot water - heat given by cold water = Heat taken by calorimeter
Solution
To determine which equation is correct, let's analyze each option step by step:
-
Heat given by hot water + heat taken by cold water = heat taken by calorimeter This equation suggests that the total heat given by the hot water and taken by the cold water is equal to the heat taken by the calorimeter. This equation is not correct because the heat taken by the cold water should be subtracted, not added, to determine the heat taken by the calorimeter.
-
Heat given by hot water - heat taken by cold water = heat taken by calorimeter This equation correctly states that the heat given by the hot water minus the heat taken by the cold water is equal to the heat taken by the calorimeter. This equation is correct.
-
Heat taken by cold water = heat taken by calorimeter + Heat given by hot water This equation suggests that the heat taken by the cold water is equal to the sum of the heat taken by the calorimeter and the heat given by the hot water. This equation is not correct because the heat given by the hot water should be subtracted, not added, to determine the heat taken by the cold water.
-
Heat taken by hot water - heat given by cold water = Heat taken by calorimeter This equation correctly states that the heat taken by the hot water minus the heat given by the cold water is equal to the heat taken by the calorimeter. This equation is correct.
Therefore, the correct equation is: Heat given by hot water - heat taken by cold water = heat taken by calorimeter
