Aquifer - answer-underground geologic unit that is saturated with water which contains sufficient permeability to yield the water to wells. Unconfined aquifer - answer-Water surface is at atmospheric pressures. Confined aquifer - answer-Aquifer that is confined by an impermeable material, such as clay or shale, resulting in the aquifer being under pressure. Permeability - answer-A measure of the ability to transmit fluids based on the material within the aquifer. Transmissivity - ans...

CHEM 103 MODULE 3 NOTES. 3.1: THERMOCHEMISTRY Thermodynamics is the study of the relationship between heat and other forms of energy, particularly mechanical work. Thermochemistry is the part of thermodynamics that deals with the quantity of heat given off or absorbed during a chemical reaction. The quantity of heat given off or absorbed during a physical change or temperature change can also be studied, and we will refer to this process as calorimetry. In order to adequately discuss thermoch...
