sketch the correct location of the "thermometer bulb" during distillation
Homework Answers
Ans. The purpose of thermometer is to monitor temperature of the distillation unit during operations.
To get correct temperature of distillation, the bulb must be nearest to the vapors arising from the distillation flask.
If the bulb is placed further apart from this point, the temperature decrease due to water-circulation assisted condensation process. The bulb shall preferable not be parallel or above the condensation line (the opening in the distillation unit to release distilled fluid).

What is the correct position of the thermometer bulb in the simple distillation apparatus? Select one: 1 inch above the bottom of the flask. 1/2 inch above the liquid level. 1/2 inch below the side-arm of the distillation head. • At the bottom of the graduated cylinder. 1 inch below the liquid level. The thermometers use alcohol now, so placement is not an issue.

Assemble the glassware for fractional distillation according to the diagram and discussion above. Make certain that all joints are secure and that the apparatus is appropriately supported. Remember to allow for space below the distillation flask for the heating mantle and below the receiving flask for an ice bath. Pay extra attention to the positioning of the bulb of the thermometer as mentioned in the introduction. It is critical that the thermometer be positioned correctly for accurate temperature measurement. Using...

Q3: The distillation column shown in the figure below is used to distill a binary mixture. Symbols x, y, z denote mole fractions of the more volatile component, while B, D, R, and F represent molar flow rates. It is desired to control distillate composition y despite disturbances in feed flow rate F. All flow rates can be measured and manipulated with the exception of F, which can only be measured. A composition analyzer provides measurements of y. (a) Propose...

4. Suppose the light bulb in the figure below is replaced with a short wire of zero resistance, and the resistance of the rails is negligible. The only resistance is from the moving rod, which is iron (resistivity - 9.90 x 10 m ). The rod has a cross-sectional area of 3.10 x 10 m. and moves with a speed of 2.60 ms. The magnetic field has a magnitude of 0.055 T. What is the current in the rod?
