Question 13 Multiple Choice (Single Answer)

What is the difference between an isothermal process and an adiabatic process?

  1. An isothermal process is a process in which the temperature of the system remains constant, while an adiabatic process is a process in which the heat content of the system remains constant.
  2. An isothermal process is a process in which the pressure of the system remains constant, while an adiabatic process is a process in which the volume of the system remains constant.
  3. An isothermal process is a process in which the entropy of the system remains constant, while an adiabatic process is a process in which the Gibbs free energy of the system remains constant.
  4. An isothermal process is a process in which the work done by the system is equal to the heat absorbed by the system, while an adiabatic process is a process in which the work done by the system is equal to the heat rejected by the system.
Question 14 Multiple Choice (Single Answer)

What is the difference between a reversible process and an irreversible process?

  1. A reversible process is a process that can be reversed without any change in the state of the system, while an irreversible process is a process that cannot be reversed without a change in the state of the system.
  2. A reversible process is a process in which the entropy of the system remains constant, while an irreversible process is a process in which the entropy of the system increases.
