A closed thermodynamic system is one in which
  • a)
    there is no energy or mass transfer across the boundary
  • b)
    there is no mass transfer, but energy transfer exists
  • c)
    there is no energy transfer, but mass transfer exists
  • d)
    both energy and mass transfer takes place across the boundary but the mass transfer is controlled by valves
Correct answer is option 'B'. Can you explain this answer?

Open system: Both mass and energy transfer takes place
Closed system: No mass transfer, energy transfer may takes place
Isolated system: Neither energy nor mass transfer takes place.

A closed thermodynamic system is one in which there is no mass transfer across the boundary, but energy transfer exists.

Explanation:
- A closed thermodynamic system is a system in which there is no mass transfer across the boundary. This means that the total mass of the system remains constant.
- However, energy transfer is allowed across the boundary. This means that the system can exchange heat and work with its surroundings.
- The boundary of a closed system may be rigid or flexible, but it does not allow the transfer of mass.
- Examples of closed thermodynamic systems include a piston-cylinder assembly, a water-filled radiator, or a sealed container of gas.
- In a closed system, the energy transfer can occur in the form of heat or work.
- Heat transfer can occur through conduction, convection, or radiation, depending on the specific system.
- Work transfer can occur due to mechanical work done on or by the system, such as compression or expansion of a gas.
- The energy transfer in a closed system obeys the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.

Summary:
- A closed thermodynamic system is one in which there is no mass transfer across the boundary, but energy transfer exists.
- The system can exchange heat and work with its surroundings, but the total mass of the system remains constant.
