Post Lab Questions
1. How would you designate the density of gas?
Density is measured by dividing the visual sense of the substance by the book of the substance. First measure the set of the empty container and then measure the mass of the container with the gas inside. The battle between the two quantitys should give you the mass of the gas alone. intentional the mass of gas you have divide that by the volume of the container it is in and that will get you the density of the gas.
2. liquid state A is red and has a larger density than liquid B that is blue in color. Liquid A and liquid B do not dissolve each other (they atomic number 18 immiscible). Describe what you expect to see when liquids are combined in a test pipe.
When two immiscible liquids are fit(p) in a test tube, the liquid with the smaller density settles on top of the liquids with the greater density. In this situation Liquid A will sink to the bottom of the test tube and Liquid B will float on top.
3. An sealed can of Coke or Pepsi will sink when position in weewee. An unopened can of Diet-Coke and Diet-Pepsi will float. Try the examine to verify the assertion. Explain the phenomenon.
Coke is a soda make of ingredients denser than water (such as sugar). However, Diet Coke ingredients (such as its insubstantial sweeteners) are less dense than water. Because of this, the denser Coke sinks in water while the less dense Diet Coke floats.
4. metre uncertainties are given in this experiment. Are they just? Explain.
The measurement uncertainties given in this experiment are not reasonable considering the quality of equipments used through tabu the experiment. Measurements were not entirely accurate. For example, scales postulate to be adjusted to get accurate readings and when measuring out of tubes and beakers we needed to rely on...If you want to get a abundant essay, order it on our website: Orderessay
