Which statement best describes the adiabatic process? a. in an adiabatic process, no heat enters or leaves the system. b. in an adiabatic process, the system does no work nor is work done on it. c. in an adiabatic process, the temperature of the system remains constant. d. in an adiabatic process, the pressure of the system remains constant.

In any adiabatic system we always say that exchange of heat in that system must be zero

so from first law we have

so we have

so here we can say that negative change in internal energy is equal to work done by the system.

so the correct answer must be

A. In an adiabatic process, no heat enters or leaves the system.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
