What is an isolated system and its role in charge conservation?

AI Thread Summary
An isolated system is defined as one that does not exchange matter or energy with its surroundings, essentially existing independently. This concept is crucial for understanding charge conservation, as the total charge within an isolated system remains constant over time. In contrast, open systems can exchange both matter and energy, while closed systems only exchange energy. The discussion highlights the uniqueness of isolated systems, likening them to entities that exist alone in the universe. Overall, the conservation of charge in isolated systems is a fundamental principle in physics.

"The charge of an isolated system is conserved"
What is the meaning of isolated system ?

hi johncena! :wink:

basically, exactly what it looks like …

nothing goes in and nothing comes out! :smile:
 
Open system exchanges matter and energy with its surrounding.
Closed systems exchanges just energy with its surroudings; e.g a Thermos
An isolated system doesn't exchange anything with its surroundings. Its like if it were alone in the universe.
 
oh, you make it sound so sad, Sakha! :cry:

Its like if it were happy in its own little universe! :smile:​

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
