steam boiler heat energy calculation

Specific Heat Calculator - Omni

This specific heat calculator is a tool that determines the heat capacity of a heated or a cooled sample. Specific heat is just the amount of thermal energy you need to supply to a sample weighing 1 kg to increase its temperature by 1 K. Read on to learn how to apply the heat capacity formula correctly to obtain a valid result.
