Multiple choice

In which of the following processes, dQ=0?

  1. Isothermal process

  2. Isobaric process

  3. Isochoric process

  4. Adiabatic process
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In this process, no heat is exchanged into or out of a system so, dQ=0. We can control heat flow either by surrounding the system with thermally insulating material or by carrying out the process so promptly that there is not enough time for ascertainable heat flow.
