According to the research, when there is little temperature difference between the top and bottom of the water column is said to be isothermal.
It is said isothermal when the relationship between the water content and the equilibrium that joins the points, present the same temperatures in the unit of time considered.
That is, the temperature of the system remains constant, being a reversible change in a thermodynamic system.
Therefore, we can conclude that according to the research, when there is little temperature difference between the top and bottom of the water column is said to be isothermal.
