Yes. In chemistry class we had to purify a water sample which was a-color. By adding charcoal and letting it sit over night, it went clear.
No, adding fluoride to water does not change its color to blue green. Fluoride is usually added in very small amounts to water supplies to help prevent tooth decay, and it should not cause a significant change in the color of the water. If water appears blue green in color, it could be due to other factors such as algae growth or presence of specific minerals.
Charcoal burning on the grill is a chemical change because the charcoal undergoes a chemical reaction with oxygen to produce heat and new chemical compounds like carbon dioxide and water vapor.
Typically, water will dilute a solution. However, that said, it also depends what you're adding the water to, ex. adding water to oil won't dilute in the same ways.
The process of adding dish soap to water in a sink is a physical change.
Yes, charcoal is denser than water. Charcoal has a higher density than water, which means that it will sink in water.
You can change the color of hydrangeas by adding water-soluble dye to their water. The dye will be absorbed by the flowers, resulting in a different color.

A charcoal or carbon water filter is among the most popular types of water filtration. The reason for this is because charcoal in nature operates as a filtration system for ground water. It naturally removed particles and contaminants without adding a distinctly chemical taste.
They made black using charcoal and water
When the color of iced tea lightens up upon adding water, it is a physical change. This is because no new substances are formed during the process; only the arrangement of the tea particles is altered, leading to the change in color.
Charcoal burning on the grill is a chemical change because the charcoal undergoes a chemical reaction with oxygen to produce heat and new chemical compounds like carbon dioxide and water vapor.
To separate charcoal and sugar, one method could involve adding water to the mixture and stirring, which would dissolve the sugar but leave the charcoal behind. Next, the mixture could be filtered to separate the dissolved sugar solution from the charcoal residue. Finally, the water could be evaporated to retrieve the sugar.
When salt is added to water to change its color, the salt dissolves in the water and does not directly affect the color of the water.
Typically, water will dilute a solution. However, that said, it also depends what you're adding the water to, ex. adding water to oil won't dilute in the same ways.
A water color painting is a painting that is created with a water based paint and extra water. The amount of water to be added to the paint depends on how much change you want to bring to the paint. Adding water changes the consistency and depth of color by making it lighter.
The process of adding dish soap to water in a sink is a physical change.
Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
