Question

An isolated system allows which of the following to enter or exit

Answer 1

I think it's A but not 100% sure though.

Answer 2

Answer:

Neither energy nor matter

Explanation:

A system is defined as the part of the universe. In thermodynamics, systems are of three types i.e.

1. Open System : In an open system, both energy and matter can freely exchange with surrounding. For example- boiling water in an open pan transfers both energy and matter.

2. Closed system : In a closed system, only energy is exchanged with the surrounding. For example- boiling water with a lid on the pan exchanges only energy with the surrounding.

3. Isolated system : In an isolated system, neither energy nor matter exchanges with the surrounding. For example : a thermos flask does not exchange energy and matter with the surrounding.

Hence, the correct option is (a) " neither energy nor matter ".
