Question

In the system (water inside an air-tight copper bottle) shown below, ______ can be exchanged with the surroundings.

  1. Open system
  2. Isolated system
  3. Heat
  4. Heat and matter

Hint:

Here only heat can be exchanged with the surrounding.

The correct answer is: Heat


    An isothermal process is a thermodynamic process in which the temperature of a system remains constant. The transfer of heat into or out of the system happens so slowly that thermal equilibrium is maintained.
