The purple color of potassium permanganate gradually spreads throughout the water in the jar by the process of diffusion.
- Diffusion is the process of movement of a substance from the region of higher concentration to the regions of lower concentration. Diffusion occurs in liquids as well as gases.
- Potassium permanganate is a purple color compound, when it is added in a jar of water it spreads throughout the water by the virtue of diffusion.
- The concentration of potassium permanganate is higher at one point and the other regions in the jar have its nil or low concentrations initially, this leads to the set up of a concentration gradient.
- As time passes diffusion occurs and the particles of potassium permanganate keep on migrating to the regions of low concentration until the concentration is uniform throughout the jar. Ultimately, it spread throughout the jar making the water purple.

Ecosystem and pond,
not sure though but good luck !
Water freezes at 0°C, the lowest possible temp for any material is absolute zero and also most of these u can just google good luck!

it will be the answer B. scientists discover new elenents.
Answer:
Energy
Explanation:
Energy from the wind transfers to the water as the water moves toward land. Like all waves, water waves only transport energy. They move only through matter, so water waves are mechanical waves.
