1.Internally reversible processes, Are there any everyday examples of this process that i would commonly see, if so what are they?
2. Can someone please explain what entropy is exactly? I get that it is related to energy and that it is generated in a system, not conserved, and that it can never be negative. But how do we quantify it? Is it similar in anyway to enthalpy?
