theres sumthing that i dont get. its the difference between a closed system and a isolated system. could some 1 plz explain and give an example of each if possible
A closed system can exchange heat and work, but not matter, with its surroundings. e.g a heater warming up a room?
An isolated system is a physical system that does not interact with its surroundings. Further reading on the isolated system here.
Hope that helps.
