Best example of an isolated system in chemistry apex

Answer;

Universe is a best example of isolated system.

-Also a perfectly isolated vacuum flask containing a hot or cold liquid is an example of an isolated system,

Explanation;

An isolated system is a thermodynamic system that cannot exchange either energy or matter outside the boundaries of the system. An isolated system differs from a closed system by the transfer of energy.

A system is isolated when there is no energy exchange with the surroundings. For example the contents of a vacuum flask are isolated. Because the hot or cold liquid in a flask is being closed off from its surrounding by the thermo bottle and there is no exchange in neither energy nor matter, the system is isolated.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
