THE loss of magnetism by ferromagnetic substances at their critical temperatures is accompanied by a striking change in the specific heat. Not only do ferromagnetic substances exhibit an abnormal rise ...

Heat is a one form of energy that runs from substance having high temperature to a substance with low temperature with respect to a specific matter. Heat is a one form of energy that runs from ...

When substances are heated, they gain heat energy. The atoms and molecules of substances gain kinetic energy and their speed increases. The average kinetic energy of these particles is proportional to ...

Last month’s article left off looking at how to verify designs through the field measurement of delivered Btu. In order to accomplish this, you’ll need to understand the basics of the Btu formulas.
