WebIndeed, the implication is that the universe must ultimately suffer a “heat death” as its entropy progressively increases toward a maximum value and all parts come into thermal equilibrium at a uniform temperature. After that point, no further changes involving the conversion of heat into useful work would be possible. WebHeat flux or thermal flux, sometimes also referred to as heat flux density [5], heat-flow density or heat flow rate intensity is a flow of energy per unit area per unit time. In SI its units are watts per square metre (W/m 2 ). It has both a direction and a magnitude, and so it is a vector quantity. bobbi\u0027s notary service new castle pa
