What distinguishes an open system from a closed system in thermodynamics?

Options

  1. AAn open system has no boundaries, while a closed system has boundaries.
  2. BAn open system allows energy exchange, while a closed system does not.
  3. CAn open system allows both energy and matter exchange, while a closed system allows only energy exchange.
  4. DAn open system has fixed boundaries, while a closed system has flexible boundaries.

Correct answer

C. An open system allows both energy and matter exchange, while a closed system allows only energy exchange.

Step-by-step solution

The key distinction between open and closed systems is that open systems allow both energy and matter exchange with the surroundings, while closed systems only allow energy exchange.
