All substances have different specific heat capacities, and these capacities can also vary depending on the state a substance is in. For instance, in a gaseous state, the specific heat of water is 2.080 Joules per gram degrees Celsius. In a liquid state, water's specific heat is 4.1813 Joules per gram degrees Celsius.

c = δQ/(mΔT) The specific heat capacity c is the amount of energy it takes to raise the temperature of one kg of material by 1 degree Kelvin or Celsius. Latent heat of fusion: δQ = Lm. The latent heat is the heat released or absorbed per unit mass by a system in a reversible isobaric-isothermal change of phase.

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.

Specific heats of solids. Theoretically, should be calculable from Eq. ( 520 ) in terms of the sound speed in the solid and the molar volume. Table 5 shows a comparison of Debye temperatures evaluated by this means with temperatures obtained empirically by fitting the law ( 532) to the low temperature variation of the heat capacity.

Specific Heat Capacity (C or S ) - The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity of the substance. The quantity of heat is frequently measured in units of Joules(J). Another property, the specific heat, is the heat capacity of the substance per gram of the substance.

So, in this simple model the specific heat approaches zero exponentially as . In reality, the specific heats of solids do not approach zero quite as quickly as suggested by Einstein's model when . The experimentally observed low temperature behaviour is more like (see Fig. 6). The reason for this discrepancy is the crude approximation that all

The specific heat capacity (or simply specific heat) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample. Informally, it is the amount of energy that must be added, in the form of heat, to one unit of mass of the substance in order to cause an increase of one unit in its temperature .
