You’ll mix food coloring with water at two different temperatures. Measure and pour ½ cup of hot water from the faucet into a glass. Then measure and pour ½ cup of cold water from the faucet into the other glass. Hold the dropper of food coloring just above the surface of the water, and carefully add one drop in the center of each glass. Wait a few minutes and then look at the glasses from the side. Place the white piece of paper behind the glasses to make it easier to see. What do you observe? Is there a difference in how it mixes?

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

explanation:

the dependant variable is spilled water

the independent is the heat
