a beaker contains 1.00 kg of water at 50.0C . what is the heat loss in kilo calories when the water cools to 20.0Cthe equation for heat = specific heat * temp change * mass and the answer is 30.0 .i dont know how to do it. Created by ?. science-mathematics-en - chemistry-en

you need to know the specific heat of water = 1Kcal/Kg or 1cal/gheat = mass x specific heat x ∆Theat = 1kg x 1Kcal/kg x 30ºC = 30Kcal
