How many BTU of heat are given off by 500 lb of aluminum when it cools from 650 degrees Fahrenheit to 75 degrees Fahrenheit? How many kilocalories of heat must be added to 750 kg of steel to raise its temperature from 75 degrees Celsius to 300 degrees Celsius? A block of copper is heated from 20.0 C to 80.0 C. How much heat in J is absorbed by the copper if itâ€™s mass is 60.0 g? How many BTU of heat are given off by 500 lb of aluminum when it cools from 650 degrees Fahrenheit to 75 degrees Fahrenheit?

How many kilocalories of heat must be added to 750 kg of steel to raise its temperature from 75 degrees Celsius to 300 degrees Celsius? A block of copper is heated from 20.0 C to 80.0 C. How much heat in J is absorbed by the copper if itâ€™s mass is 60.0 g? Solution Solving first question C=specific heat capacity of aluminium=0.215btu/lb.F So total heat =m*c*difference in temperature Heat=61812.5 btu .
