Justify Equation 6.3 by integration. (b) Consider the thermal energy in an aquifer for which the rocks have a porosity 0.2, a density 3000 kg/ m3, and a specific heat 1000 J/kg-K, and for which the fluid is water.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix. b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds. c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.
