ad·i·a·bat·ic

(ăd′ē-ə-băt′ĭk, ā′dī-ə-)

adj.

Of, relating to, or being a reversible thermodynamic process that occurs without gain or loss of heat and without a change in entropy.

[From Greek adiabatos, impassable : a-, not; see a-¹ + diabatos, passable (dia-, dia- + batos, passable, from bainein, to go; see g^wā- in Indo-European roots).]

ad′i·a·bat′i·cal·ly adv.

adiabatic

(ˌædɪəˈbætɪk; ˌeɪ-)

adj

(General Physics) (of a thermodynamic process) taking place without loss or gain of heat

(General Physics) a curve or surface on a graph representing the changes in two or more characteristics (such as pressure and volume) of a system undergoing an adiabatic process

[C19: from Greek adiabatos not to be crossed, impassable (to heat), from a-¹ + diabatos passable, from dia- across + bainein to go]
