internal energy - ΔU = Uf − Ui First Law of Thermodynamics - ΔU = q + w heat - substances not changing phase (per gram) - q = m⋅Cs⋅ΔT heat - substances not changing phase (per mol) - q = n⋅Cm⋅ΔT heat - substances that are changing phase (per gram) - q = m⋅ΔHtrans heat - substances that are changing phase (per mol) - q = n⋅ΔHtrans work - constant external pressure (Pext) - w = −PextΔV work - constant external pressure (Δngas) - ...

System - ANSWER-A system in thermodynamics is a space that may be defined as being isolated, meaning unable to exchange energy and matter with its environment, or closed, meaning it can exchange energy but not matter, and an open system that can exchange both. Any system contain internal energy that is defined by the state of that system. This thermodynamic state can be described by all substances and any two of the three variables: temperature, pressure, and volume. In an open or closed ...
