Expert
The three facts on evaporation are as follows:
a) 80 percent of evaporation comes from ocean.b) 20 percent of evaporation comes from internal water.c) The wind helps evaporation through moving it.

Energy changes in some chemical reactions can be used to deduce the energies of chemical bonds. Our understanding of the molecular basis of thermodynamic properties is extended when we ask why the enthalpy change for a reaction is what it is. We deduce,
The temperature reliance of internal energy and enthalpy depends on the heat capacities at constant volume and constant pressure. The internal energy and enthalpy of chemical systems and the energy changes that accompany chemical reactions depend on the
