Mock Test Question

Group Answer

The liquid A (Red) is poured at the same time as the liquid B (Green), which we assumed are at the same temperature.
The spaces between the molecules of the liquid A are larger, thus it is less denser than liquid B , which will cause it to have a lesser weight and float up above liquid B.The spaces between the molecules of liquid B is smaller, thus it is more dense and would cause it to have more weight and therefore sink bloew liquid A.

Notes

Observation: After experiment the two liquids mixes up together - shows that the assumption on their same initial temperature isn't really right. The pbservation could have been because of they reaching thermal equilibrium, where the kinetic energy between the molecules of both liquids stops when both of them has the equal average amount of kinetic energy between the molecules.
