Which type of wall is present in the closed system?

The Correct answer is Adiabatic Wall.

Key Points

• An adiabatic wall is a type of boundary that does not allow the transfer of heat energy between a system and its surroundings.
• It is a crucial feature in a closed system, ensuring that the system remains thermally isolated.
• The term "adiabatic" is derived from the Greek word "adiabatos," meaning impassable, referring to the prevention of thermal interaction.
• In thermodynamics, an adiabatic wall is used to study processes where the system does not exchange heat with its environment, such as adiabatic processes.
• These walls are essential in applications like insulated containers, where maintaining temperature without external influence is required.
• Adiabatic walls help in analyzing energy changes in terms of internal energy, pressure, and volume without involving heat transfer.
• Such systems are commonly modeled in laboratories to understand theoretical concepts of thermodynamics.

 Additional Information

• Permeable Wall
  • A permeable wall allows the exchange of matter between the system and its surroundings.
  • Such walls are used in systems where flow or diffusion of substances is studied, like a semi-permeable membrane in biological systems.
• Semi-permeable Wall
  • A semi-permeable wall selectively allows certain particles or substances to pass through while blocking others.
  • These walls are commonly found in applications such as osmosis and reverse osmosis systems.
• Diathermal Wall
  • A diathermal wall permits the transfer of heat between the system and its surroundings.
  • These walls are used in systems where temperature equilibrium is studied, such as heat exchangers.
