what is the formula for calculating energy changes using specific heat capacity. Energy transferred mass of water heated specific heat capacity of water temperature rise 100 42 20 8400 J It is also useful to remember that 1 kilojoule 1 kJ equals 1000 J. Use the formula q mcDT where q heat energy m mass c specific heat DT change in temperature Putting the numbers into the equation yields.

Definition of Specific heat capacity revealed that it is the amount of heat required to increase the temperature of 1 kilogram of any substance by 1 kelvin. Calculate the amount of heat needed to increase the temperature of 250g of water from 20C to 46C. C Q m x DT Q supplied or subtracted heat in joules M the samples mass DT initial and final temperature difference JkgK heat capacity measurement type Specific Heat Values The heat capacity calculator is going to be useful in many situations.
Heat capacity E T where E is the amount of heat energy supplied and T is the change in temperature.
By using the formula of specific heat. Specific heat capacity is expressed with units J kg-1 C-1 or J kg-1 K-1. D T change in temperature. However you may not need it in the case of typical specific heat values.
