9 Which of these process is always exothermic?

A general rule of thumb is Exothermic reactions create a decrease in disorder Let's use this: 1 This goes from a solid to a liquid liquids have more disorder than solids This is endothermic 2 This goes from a gas to a liquid gases have more disorder than solids This is exothermic 3 This goes from a liquid to a gas This is endothermic

Exothermic process — Wikipedia Republished // WIKI 2

In thermodynamics the term exothermic process (exo- : outside) describes a process or reaction that releases energy from the system to its surroundings usually in the form of heat but also in a form of light (e g a spark flame or flash) electricity (e g a battery) or sound (e g explosion heard when burning hydrogen) Its etymology stems from the Greek prefix έξω (exō which

Can an exothermic (endothermic) process increase

We classify exothermic and endothermic processes based on enthalpy change $Delta H 0$ and $Delta H 0$ respectively I assume this translates to $Delta U 0$ and $Delta U 0$ respectively for most processes (where $Delta H = Delta U + Delta (PV)$ in general) But not all? In which case we might have processes where $Delta H 0$ (exothermic) but $Delta U 0$?
