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 gwā- 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
n
(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]
