The heat equation is a parabolic partial differential equation that describes the distribution of heat (or variation in temperature) in a given region over time.
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. A difference in temperature of the substance produces heat or energy transfer. Heat is related to the amount of matter also.. If heat is present to a matter, it increases its temperature or phase. The specific heat is the quantity of heat per unit mass necessary to increase the temperature by one degree Celsius and is given in the formula: Table for Specific Heat of Different Substances.
