Isotherm
Isotherm explained in an easy to understand way:
Imagine trying to adjust the thermostat so that every room in your house feels equally comfortable. This is similar to how an isotherm works, as it connects all the locations that share the same temperature on a weather map, much like ensuring every room is at the same desired warmth. Just as you want each room to have the same cozy temperature, an isotherm links points that have achieved this temperature balance, creating a 'comfort zone' across different areas.
