J = Nm. As F = ma, which in units is, N = kg(m/s2) and P.E .= mgh, in units is, J = kg(m/s2) x m . substituting into J = Nm gives: kg(m/s2) x m = kg(m/s2) x m. These are the same so the equation is homogeneous. Vectors. Introduction of Vectors. A . vector. is a quantity, which has both a magnitude and a direction. Vectors arise naturally as ...

The latent heat is written as L and given in J/kg in mks units. It literally means how much heat energy must be added to a mass of material to convert its phase such as from solid to liquid (melt), liquid to vapor (evaporate) or solid to vapor (sublimate). DQ = m L.

5x105 kg 4.2x103 J/kg/K 1.25x10-2 K/year = 0.8 W. The 4 W/m2 we used in the homework was the . decrease. in IR to space resulting from an instantaneous doubling of CO2. This 0.8 W/m2 flux is the downward increase in IR minus the increase in the fluxes cooling the ocean due to dry convection, evaporation, and radiative fluxes at the top of the ...
