4 basic laws of thermodynamics correct answers zeroth law: states that 2 objects in thermodynamic equilibrium with a 3rd object are also in equilibrium with each other 1st law: states that neither mass nor energy can be destroyed; only converted from 1 form to another(conservation of energy) 2nd law: states that the entropy of an isolated system can only increase; heat is not transferred from low temp system to a higher temp system one unless additional work is done 3rd law: states that...

Field Capacity (FC) - ANSWER The amount of water retained in soil after it has been saturated and allowed to drain freely for two or three days. At field capacity, the forces holding water to soil particles are approximately equal to the downward forces of gravitational pull.
