EEE 350 EXAM QUESTIONS WELL ANSWERED LATEST UPDATE 2026 environmental sustainability - Answers everything that we need for our survival/well-being depends directly or indirectly on our natural environment alkalinity - Answers measure of a water's capacity to neutralize acids adsorption - Answers chemical adsorbs to the surface absorption - Answers chemical absorbs (partitions) into a phase (3D) organic compounds (OC) - Answers many are hydrophobic, energetically unfavorable compounds to be dissolved in water sorption - Answers influences mobility, natural degradation, and engineered remediation of pollutants sorbate - Answers substance being captured, sticking to or soaking into sorbent sorbent - Answers solid material that does the capturing 1/n 1 - Answers surface becomes saturated 1/n 1 - Answers sorbate modifies original surface + enhances sorption octanol - Answers surrogate for tissue or some fluids in animals or organic carbon on soil partitioning - Answers determines the fate of compound after it enters environment batch reactor - Answers no mass flows into or out of the reactor change in concentration results from chemical reaction only ex: sealed beaker d[C]/dt= -k[C]^n completely mixed flow (CMFR) - Answers concentration at any location within reactor volume is constant C_out = C_in / (1+kv/Q) Ct/Co = e^-(Q/v + k )t plug flow reactor (PFR) - Answers not mixing between plugs as they move through the reactor net chemical reaction within the plug V(dC/dt) = -VkC Ct/Co = e^-kt which reactor is more efficient? - Answers PFR is more efficient but CMFR is more common since it can handle the spikes in flow better have the same flow rate, kinetics, order but better performance is the lower C_out/C_in ratio and the lower the volume needed the better heat internal energy - Answers delta E = mc(T2-T1) MCAT chemical internal energy - Answers delta E = delta H rxn at constant volume chemical bonds - ex: combustion of hydrocarbon fuels, metabolism of food molecular interactions - overcoming intermolecular forces in liquid (H2O (l) to water vapor), overcoming in solid heat + heat capacity - Answers water's heat capacity is higher than other liquids oceans help moderate surface temp temp buffer prevents large, rapid changes in temp + protects aquatic organisms heat loss - Answers (1/R)(A)(t) infiltration heat loss - Answers V(infiltration rate)(heat to raise temp of air 1 degree F) how to reduce heat loss in buildings - Answers thermal storage walls, ventilation, overhangs evapotranspiration - Answers water is transferred land to atmosphere through evaporation from soil + plants energy balance for urban heat islands - Answers deltaQs = (net radiation) + (anthropogenic heat) - (sensible heat flux) - (evapotranspiration) obligate anaerobes - Answers require no oxygen facultative anaerobes - Answers can survive with or without oxygen, uses aerobic respiration with oxygen present since its more efficient primary producers - Answers autotrophs + foundation of ecosystems; primarily plants, phytoplankton, produce their own food using photosynthesis primary consumer - Answers primarily get energy/food from primary producers; herbivores secondary consumer - Answers primarily get energy/food from primary consumer, are carnivores or omnivores tertiary consumer - Answers top of the food chain and have few predators, primarily get energy/food from secondary consumers lots of energy loss from primary producer oxygen demand - Answers reduced carbon compounds in water exert oxygen demand compounds generally not toxic water pollution control tech reduces concentration of these compounds before discharged to prevent depletion in surface waters BOD - Answers biochemical oxygen demand - amount of O utilized by microorganisms in oxidizing carbonaceous + nitrogenous organic matter aggregate measure of oxygen consumption by microbes when they metabolize the organic compounds CBOD - Answers carbonaceous biochemical oxygen demand - when electron donor is carbonaceous organic matter Lo= y_t/ (1-e^(-k_L*t)) NBOD - Answers nitrogenous biochemical oxygen demand - when electron donor is nitrogenous organic matter ThOD - Answers theoretical oxygen demand - amount of oxygen utilized by microorganisms in oxidizing carbonaceous/nitrogenous organic matter
