... Comes from the total kinetic and potential energy of molecules which compose the system. Change in internal energy (U or E) : energy change as system goes from an initial state with energy Ui to a final state with energy Uf. Hence U = Uf – Ui. We suppose that a closed system undergoes a process b ...

... States of Matter: We classify matter into several states because it helps us classify information in a systematic way. Solid State: Solids are rigid. They have definite shapes. The dimensions of solids change slightly with temperature and pressure. Liquid State: Liquids flow and assume the shape of ...
