  3. Is the volume held changeable in an isochoric process?
  4. When does an isothermal process occur?
  5. What is an adiabatic process?
  6. What is this process identical to for a reversible process?

  1. 2.    Insert a necessary proposition:
  2. An isobaric process occurs … constant pressure.
  3. The pressure inside the cylinder is always … atmospheric pressure, although it is isolated from the atmosphere.
  4. The system is dynamically connected, …  a movable boundary, … a constant-pressure reservoir.
  5. An isochoric process is one in which the volume is held constant, meaning that the work done … the system will be zero.
  6. Any heat energy transferred … the system externally will be absorbed as internal energy.
  7. An example would be to place a closed tin can containing only air … a fire.
  8. An isochoric process is also known … anisometric process or an isovolumetric process.
  9. An example an isothermal process would be to have a system immersed … a large constant-temperature bath.
  10. Any work energy performed … the system will be lost to the bath, but its temperature will remain constant.

10.An adiabatic process is a process in which there is no energy added or subtracted … the system by heating or cooling.

11.… a reversible process, this is identical to an isentropic process.

12.The system is thermally insulated … its environment and that its boundary is a thermal insulator.

13. … certain conditions two states of a system may be considered adiabatically accessible.

14.An isentropic process occurs … constant entropy.

15.A process of cooling may be required to maintain that value … entropy.
