Question 1: chemistry then and now (16 points) a. lavoisier was a chemist in the 1700s. he took a very systematic approach to measurements in chemistry and is considered to be the "father of modern chemistry." scientists today also take a very systematic approach by using the scientific method in their research. (6 points) i. fill in the missing steps of the scientific method. (4 points) a. state the question b. c. conduct an experiment d.

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.
