Example 1: The expansion of the gas at constant temperature
.For example, the expansion of a perfect gas. By a constant temperature (isothermal expansion of perfect gas) that is consistent with the change in entropy, however. (This change is consistent with the firstFrom Equation 2 it follows that at constant temperature

Example 1: the expansion of a gas at constant temperature
.An example of an expansion of a perfect gas at constant temperature with the birth (isothermal expansion of perfect gas) that is consistent with the change in entropy (this change corresponds to the first image. From the equation 2 it becomes a constant temperature that is

Example 1: the expansion of the gas constant temperature
An example of a perfect gas, the growth rate of a constant temperature (isothermal expansion of perfect gas) that will be consistent with the changes in how lean call (the changes in accordance with this first imagefrom the equation of 2. That will be a constant temperature
