A line on a graph that shows a process where no heat goes in or out
  • noun
  • /ˈeɪdiəˌbæt/
  • Specialized
: adiabática
  • In thermodynamics, the dry adiabat shows how temperature changes without heat exchange in the atmosphere.

Examples

  • The texts I've seen all suggest that convection is required to establish the dry adiabat lapse rate. e.g. 39;12210;TOOLONG ... page 13.

  • Namely, it has to do with the fact that the lapse rate in the tropical atmosphere is basically expected to be pegged to the moist adiabat.

  • Under such conditions, convection is suppressed and the dry adiabat temperature profile cannot be established.

  • During the experiment, we plotted the adiabat to illustrate the temperature drop in a closed system.

  • To analyze the system's behavior, we drew the adiabat on the thermodynamic diagram, reflecting no heat transfer.

Etymology

Adiabat comes from Greek parts a- meaning 'not' and diabatos meaning 'passable', which is like the English word 'pass'. So an adiabat is a path where heat does not 'pass' — a process with no heat exchange.
