The Assertion "An isolated system is the one which can neither exchange matter nor energy with the surroundings" is true.
However, the Reason "It should be noted that every system is perfectly isolated" is false. Not every system is isolated, as there are systems that can exchange energy with the surroundings, known as open systems, and systems that can exchange both energy and matter with the surroundings, known as closed systems.
An isolated system is a thermodynamic system that does not exchange energy or matter with its surroundings. In other words, the system is completely self-contained, and there is no transfer of heat, work, or mass between the system and its environment. This means that the internal energy of an isolated system remains constant.
The given assertion is true since it correctly defines an isolated system as one that cannot exchange matter or energy with the surroundings.
The reason given in the statement, "every system is perfectly isolated," is false. This is because not every system is isolated - there are many systems that can exchange energy or matter with their surroundings. For example, an open system allows for both energy and matter exchange, while a closed system allows for only energy exchange.
Therefore, the correct answer is "Assertion is true but reason is false."
Therefore, the correct answer is option (C) Assertion is true but reason is false.
