Concept in Definition ABC

The isotherm is an element and a tool which is essential when it comes to measurement of the temperature of a certain area. On a cartographic plane, the isotherm is a curve that joins those points that present the same temperatures in a Unit time considered.

Thus, for the same area, a large number of blueprints that contain isotherms, for example, isotherms of a long-term average temperature of the months of January, February, among others, or the isotherms of annual average temperatures.

On the other hand, the term is used to refer that this or that thing has the same temperature or a temperature that is characterized by staying constant over time.

For his part, isothermal process or isothermal process, turns out to be the reversible temperature change in a thermodynamic system, the aforementioned change being constant for the entire system. An example of the action of this process is compression or expansion of a gas ideal which is in Contact permanent with a thermostat; the gas is placed so that it makes thermal contact with another system of large heat capacity and that is at the same temperature as the gas. The

hot it will transfer very slowly making it easier for the gas to expand.
