Isolated System

Postby Dakota_Campbell_1C » Fri Feb 08, 2019 12:32 am

What is the point of an Isolated system? If no matter or heat can leave or enter the system and the heat and mass stay constant what would be the interest in using an Isolated system?

An isolated system is useful to calculate changes that happen based solely on the reaction and not due to exchanges with the surrounding

Isolated systems take away any other factors that can be impacting the reaction.

Since the change n internal energy (delta U) is q plus w. In an isolated system you don't have any work being done so you can disregard w and that leaves you with q. So by studying isolated systems we can see how q changes on its own due to the reaction occurring.

In an isolated system, no energy or matter leave the system right? However in a closed system energy can leave the system?

yes, in a closed system, energy can enter and leave freely.
