what is the difference between oil,mercury and red water on barometer?

Expert Solution

In general, the instrument called barometer is used to measure the atmospheric pressure. The instrument uses the specific fluid and a tube. To determine the atmospheric pressure we generally measured the height coloumn of fluid in the tube above the surface in the container in which that tube is placed. The atmospheric pressure is related as P = . So, if we use the different fluid of different density the Height of cloumn will differ. For the same atmospheric pressure if we use the fluid of Lower density the height should be large so we require a large tube which is quite un-practical. If the tube will insufficient in length the device will not work appreciablly.

For example : The atmospheric pressure is often given as the length of mercury column in a barometer. a pressure of 76 cm of mercury means 1 atm in barometer. This height will change for different fluid.

1) Mercury (Hg) can be used in a barometer to measure air pressure, based on how tall a column of mercury can be supported by the pressure of the atmosphere or another gas sample. The barometric reading taken at Skyline College on a specific day was 743.8 mm Hg. If the interior circumference of the tube holding the mercury is 9.82 mm, what is the mass of mercury in the tube (above the pool of mercury)? The column may be...

Prediction: Form a hypothesis addressing: Between water and canola oil, what do the density graphs look like plotted together and how are they related to viscosity? Support your hypothesis with some justification including graphs. Specifically, draw a graph of mass vs. density for the two fluids and the other graph should represent the second question in the best way you can.
