... b. Suppose that the gas expands at the expense of its energy, however, a heat bath is in contact with the system compensating for the loss in energy. What happens to the density of the gas? c. Density therefore depends on the state variables. In oceanography, a term called isopycnalis isopycnalis us ...

Some ideas from thermodynamics
... system is restored to its original state and the engine is in a position to repeat these actions. The key to getting the most work possible for a given heat input is to make all parts of the cycle reversible. That is, when heat is moved from the source to the engine, it is done with the engine at th ...

The Laws of Thermodynamics
... dS is independent of the path. Some text books refer to dS therefore as being an exact differential. In general the change in entropy between any two arbitrary states depends only on those states and not on the path between them. We can write an infinitesimal version of the first law informally as d ...
