Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. The units in which work is expressed are the same as those for e
Descriptions of the state and movement of heat and mass within soil using units conforming to the International System of Units (SI) are discussed. We propose that gas and water flux densities should be expressed in terms of kg m -2 s -1 and heat flux densities in terms of W m -2. ...
