Introduction to the Second Law of Thermodynamics Heat

Figure 1.These ice floes melt during the Arctic summer.Some of them refreeze in the winter,but the second law of thermodynamics predicts that it would be extremely unlikely for the water molecules contained in these particular floes to reform the distinctive alligator-like shape they formed when the picture was taken in the summer of 2009.Flow Rate and Its Relation to Velocity Physicswhere V is the volume and t is the elapsed time.The SI unit for flow rate is m 3 /s,but a number of other units for Q are in common use.For example,the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min).Note that a liter (L) is 1/1000 of a cubic meter or 1000 cubic centimeters (10-3 m 3 or 10 3 cm 3).In this text we shall use whatever metric units are most Enthalpy - Chemistry LibreTextsAug 15,2020 Difference between ��H and q?
