isothermal

Explanation:isothermal can be defined as a line on a map or chart of the earth's surface connecting points having the same temperature at a given time or the same mean temperature for a given period.

An isothermal process is a change of a system, in which the temperature remains constant: ΔT =0. ... In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0).
