- Adiabatic closed system
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
A thermo flask is considered an isolated system because it does not exchange matter or energy heat with its surroundings It is designed to minimize heat transfer keeping the contents at a constant temperature over time
