Internal Energy of isolated system

Postby 504939134 » Sun Feb 02, 2020 9:34 pm

In terms of delta U, why does it remain 0. Why does work + heat equal 0 in isolated systems?

An isolated system has a constant internal energy because no matter or heat can be physically exchanged with the system. In other terms, the heat and work of the system can't be changed, thee internal energy remains constant.

Because the system can't interact and be affected by or affect its surroundings.
