Hint :Isotherms are commonly used in meteorology. Meteorology is the study of the Earth's atmosphere and the temperature and moisture patterns that cause various weather conditions. Precipitation, thunderstorms, tornadoes, hurricanes, and typhoons are only a few of the major topics of research.

Complete Step By Step Answer:
An isothermal process is one in which the temperature of a system stays constant. That is, $\Delta T =0$ An isotherm is a type of curve. An isotherm is a line drawn on a map or chart that connects points of equal temperature. That is, the temperature values are the same at any point along an isotherm. In the Weather Visualizer, isotherms are represented by dashed orange contours. In meteorology, isotherms are generally used to depict the distribution of temperature at the Earth's surface or to indicate constant level or constant pressure on a map. This integral equals the area under the relevant pressure-volume isotherm for an isothermal, reversible phase, and is shown in blue for an ideal gas. For this isothermal transition, the blue area reflects the "job" performed by the gas during expansion.

Note :
In thermodynamics, an isotherm is a curve on a p-V diagram that represents an isothermal phase. In other words we can say that an isotherm is a line on a graph that represents changes in volume or pressure under constant temperature conditions. For instance, an ideal gas that expands while maintaining a constant temperature, known as the isothermal process will exist in a different state.
