Which term is incorrectly defined?

a) linear range: the range over which the response of an analytical method is proportional to analyte concentration
b) corrected absorbance: the average absorbance of the blanks is subtracted from each measured absorbance
c) blank solution: solution containing all reagents and solvents used in the analysis to which no analyte is deliberately added
d) standard solutions: solutions for which the standard deviation is known
e) dynamic range: concentration range over which there is a measurable response to analyte, though the response is not linear

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
