- An isolated system is one in which neither energy nor mass is allowed to cross the boundary of the system.
- Let's have an imaginary thermos flask insulated with a material of infinite thermal resistance.
- This Thermos flask when closed with a knob can not transfer mass and energy.
- Obviously, this is an imaginary system because in practical engineering applications there does not exist any material with an infinite thermal resistance (or zero thermal conductivity)
