Heat and Thermodynamics
... The internal energy U might be thought of as the energy required to create a system in the absence of changes in temperature or volume. But if the process changes the volume, as in a chemical reaction which produces a gaseous product, then work must be done to produce the change in volume. For a co ...

... An absolutely central concept is thermal equilibrium. Equilibrium is any state a system is in once it has stopped exchanging heat with its surroundings; or, if it has no surroundings (= is isolated), once it has settled down to a macroscopically unchanging state. (Feynman: “equilibrium is when all t ...

Entropy Rate Balance for Control Volumes Comment: The value of the entropy production for a single component such as the throttling valve considered here often does not have much significance by itself. The significance of the entropy production of any component is normally determined through compa ...

... A state variable describes the state of a system at time t, but it does not reveal how the system was put into that state. Examples of state variables: pressure, temperature, volume, number of moles, and internal energy. Thermal processes can change the state of a system. We assume that thermal proc ...
