Detailed explanation-1: -formation of covalent bonds between hydrogen and oxygen molecules The process helped the carnations to change color-C. cohesion and adhesion of water molecules. Water has unique properties that make it a universal solvent.

Detailed explanation-2: -White carnation petals will turn the color of the dyed water because of capillary action within the plant.

Detailed explanation-3: -Dyeing carnations will work best with at least 20 to 30 drops of food coloring. It’s pretty hard to go overboard, it’s a simple equation when it comes to flower dyeing: The more food coloring, the more the color will show up in the flower.

Detailed explanation-4: -Three properties of a water molecule enable it to move from the root system to the leaves of the plant. They are cohesion, adhesion, and high surface tension. Water molecules are polar as they contain hydrogen bonds. Water molecules can attract one another and this is called cohesion.

Detailed explanation-5: -Cohesion is intermolecular forces between like molecules; this is why water molecules are able to hold themselves together in a drop. Water molecules are very cohesive because of the molecule’s polarity. This is why you can fill a glass of water just barely above the rim without it spilling.
