The heat equation is an important partial differential equation that describes the distribution of heat (or variation in temperature) in a given region over time. In some cases, exact solutions of the equation are available; [24] in other cases the equation must be solved numerically using computational methods such as DEM-based models for ...

In 1856, Rudolf Clausius, referring to closed systems, in which transfers of matter do not occur, defined the second fundamental theorem (the second law of thermodynamics) in the mechanical theory of heat (thermodynamics): "if two transformations which, without necessitating any other permanent change, can mutually replace one another, be called equivalent, then the generations of the …

Specific heat is also sometimes referred to as massic heat capacity. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. The SI unit of specific heat …

Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to an object to produce a unit change in its temperature. The SI unit of heat capacity is joule per kelvin (J/K).. Heat capacity is an extensive property.The corresponding intensive property is the specific heat capacity, found by dividing the heat capacity of an object …

the matrix A governing heat transfer. Do the eigenvectors of the matrix have physical meaning? ie. do they yield the direction of highest heat flow? --24.84.203.193 28 June 2005 05:21 (UTC) Clarification. I think it might be a good idea for someone to explain what situations the heat equation works in.
