LIFE SCIENCE

Detailed explanation-1: -A system which can neither exchange matter nor energy with the surroundings called as isolated system . Since the boundary is sealed and isolated, there is no interaction between system and surrounding. Ice in an ideal thermos flask represents an isolated system.

Detailed explanation-2: -An isolated system is one that cannot exchange either matter or energy with its surroundings.

Detailed explanation-3: -An isolated system is that which can exchange energy but not matter with the surroundings.

Detailed explanation-4: -An isolated system is a thermodynamic system that cannot exchange either energy or matter (mass) outside the boundaries of the system. An isolated system differs from a closed system by the transfer of energy. Closed systems are only closed to matter, energy can be exchanged across the system’s boundaries.

Detailed explanation-5: -A thermos flask is the best example of an isolated system. A thermos flask is used to keep things either cold or hot. Thus a thermos does not allow energy for transfer.
