CONCEPT:

Types of Systems in Thermodynamics

  • In thermodynamics, systems are classified based on the exchange of energy and matter with their surroundings.
  • There are three main types of systems:
    • Open System: Both energy and matter can be exchanged with the surroundings.
    • Isolated System: Neither energy nor matter can be exchanged with the surroundings.
    • Closed System: Only energy can be exchanged with the surroundings, but not matter.
    • Adiabatic System: No heat exchange occurs with the surroundings, but work and matter can be exchanged in some contexts.

EXPLANATION:

  • Based on the definitions of the different types of systems:
    • An Open System allows both energy and matter to be exchanged.
    • An Isolated System does not allow either energy or matter to be exchanged.
    • A Closed System allows the exchange of energy but not matter.
    • An Adiabatic System does not allow heat exchange but may allow other forms of energy and matter to be exchanged.
  • The correct answer is a Closed System.

Therefore, the correct answer is Option 3: Closed system.
