What is the unit of measurement for heat?
First scientists used calorie as the unit of heat energy. One calorie is the amount of heat required to raise the temperature of one gram of water through one degree celcius. So 1000 cal is taken as kilo calorie. Even now a days we use such units in case of biological energy. Later scientists have found that heat is also a kind of energy which is closely related to mechanical energy as 1 cal = 4.18 joule So k cal requires 4180 joule of energy. This is what we call mechanical equivalent of heat energy. So at present stage we use only joule as the unit of heat energy. Especially in chemistry they use kilojoule/mole etc.
How much heat is required to convert 75 g of ice from 0 C to liquid water at 90 C answer in cal?
Heat of fusion is absorbed Q = mLf = 75x 80 = 6000 cal just to melt the ice Heat is absorbed to change temp Q = mC(delta)T = 75 x 1 x (90 - 0) = 6750 cal Total heat = 6000 + 6750 = 12750 calories
