Isolated System Drawing

Postby Alison Trinh 1E » Sun Feb 02, 2020 11:43 pm

Can someone explain the isolated system drawing Dr. Lavelle drew in lecture? What does the cloud-like drawing surrounding the flask represent?

Basically, an isolated system can't exchange matter or heat with its surroundings. The cloud-like drawing around the flask represents insulation, and it's meant to convey that heat isn't being exchanged with the surroundings.

He was trying to draw a puffer jacket! Insulation prevents a system from transferring energy or matter with its surroundings. Some examples of an isolated system are a bomb calorimeter and a thermos container.

In an isolated system, the system cannot exchange matter nor energy with the surroundings. So basically an isolated system is usually sealed, rigid, and has thermally insulating walls such as a thermos container. The image below visually shows the difference between the three types of thermodynamic systems. Image
