The small pores of this membrane are restrictive to such organic compounds as salt and other natural minerals, which generally have a larger molecular composition than water. These pores are also restrictive to bacteria and disease-causing pathogens. ...

... work is done. In this case we have Q = ∆U so that one can measure the change in the observable U to get at the heat. What observable can we use to measure heat when there is work done? Well, it depends upon precisely how the work is done. An observable that can be used for measuring heat for isobari ...
