Yes, the data from mass spectrometry has helped modern scientists to make modifications to Dalton's model.
Dalton's model consisted of a single atom and that basically the atom is the smallest object. At the time, no discovered what are inside of atoms.
Atoms are made up of small particles, protons, neutrons and electrons. A mass spectrometer is an instrument that is able to see what is inside an atom. With this item, scientists have proved that atoms are not the smallest in the world cause the objects in them are smaller.
Answer:
Projective tests are a type of personality test that is designed to have a person react to ambiguous stimuli to potentially reveal hidden emotions that are projected onto the test. In the Rorschach Inkblot Test a person is shown a series of ten black and white cards and asked to report the first thing that comes to mind. The participant then says what came to mind and may project some emotions onto the inkblot that were previous unmentioned. The person administering the test then records aspects of their reactions like gestures and tone of voice. In a thematic apperception test or TAT a person is shown an ambiguous scene and asked to create a story around it. The person can then reveal emotions that they did not previous mention in the story by stating how the characters feel and how the story ends. In a projective test a lot is up for interpretation based on the individual and how they are feeling at that time making the test lack both reliability and validity because of no grading scale being set in stone and results being inconsistent.

__Dry and Liquid Measurements__
Explanation:
Density is defined as a material per unit volume of the material.
The determination of the density of a liquid with an aerometer is based on the principle of Archimedes' law: "Any object that is immersed in a liquid will experience a lift which is equal to the weight of the liquid being moved".
The aerometer is in the form of a hollow cylinder, so that the aerometer can be immersed in the right position (the scale is immersed in liquid), then the aerometer is filled with Pb grains. The scale on the aerometer shows the density of the liquid, the smaller the density of the liquid, the deeper the aerometer will be. Therefore the aerometer scale shows an increasing number from top to bottom.
