The diagram shows a process that is used to separate gypsum from shale on the basis of density. Crushed rock is dropped into a mixture of liquid and small particles, called a slurry. The data tables show the mass and volume of three samples of gypsum and three samples of shale after they were separated by this
process.
Since gypsum floats and shale sinks in the slurry, which sequence shows the substances arranged in order from least dense to most dense.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
