Three beakers are of identical shape and size , one beaker is pained matt black, one is dull white and one is gloss white . The beakers are filled with boiling waterin which beaker does the water cool more quickly? Give reason. ( i really need the answer quickly)

The beaker that is matt black heats more quickly because black attracts more heat.

Explanation:

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
