Specific Heat Pdf

When there is no air movement. National Institute for Occupational Safety and Health. Then the change in temperature will depends on the particular path that the system followed through its phase space between the initial and final states. They include gravitating objects such as stars and galaxies, and also sometimes some nano-scale clusters of a few tens of atoms, close to a phase transition.

However, this computation is valid only all parts of the object are at the same external pressure before and after the measurement. Dividing by the amount of substance in moles yields its molar heat capacity. However, several other units of measure have been used for this quantity in the past, and are still used in certain contexts.
