For an adiabatic change in a system, the condition which is applicable is

Options

  1. Aq=0
  2. Bq=-w
  3. Cq=w
  4. Dw=0

Correct answer

A. q=0

Step-by-step solution

The first law of thermodynamics is given by the equation U = q + w , where U is the change in internal energy, q is the heat exchanged, and w is the work done. An adiabatic process is defined as a process in which there is no exchange of heat between the system and its surroundings. Therefore, for an adiabatic process, q = 0 . Answer: q=0
