Why does the Clausius inequality involve a single term/integral if we consider a body interacting with multiple heat sources/sinks?

But if you're interacting with outside code, like when you're returning a list from a method, then you only want to declare the interface without necessarily tying C# IList Kullanımı yourself to a specific implementation, especially if you have no control over who compiles against your code afterward.

I leave C# IList Kullanımı this up to show that if you needed to do it (e.g. the off chance a third party library returned a List that you needed to convert for another 3rd party library), you yaşama do it this way.

In particular, IList lets you use the indexer, and add/remove items; things that IEnumerable don't let you do.

There is a complication though that dynamic yaşama't see explicit implementations, so something gönül implement IList and IList-of-T and yet still be completely unusable from dynamic.
