Why is white and shiny surface suitable for fridge-freezer?
White reflects heat,thereforereducing heat radiation to keep the fridge or freezer cool
Why does a black can cool down faster than a white can?
The reason something looks black to us is because it reflects less light - therefore, the light is absorbed. The energy of the absorbed light, of course, heats the object up. Please note that black objects also tend to emit thermal radiation faster - so if there is no sunlight, they will get cold faster.
Why will milk in a saucer cool faster than milk in a glass?
Cooling due to simple evaporation at a surface is clearly simpler when the surface is large, such as the saucer. The cooling is due to the molecules that have more energy breaking free of the surface. Hence the average temperature of the remainder lowers.
Does sand or air cool faster?
air
Does water or sand cool faster after dark?
Sand cools down faster after dark
Which kettle would cool down faster a black shiny kettle or a shiny metallic kettle?
shiny because its cool when after boiled also the black wouldnt cool as it attracts heat.
When the sun goes down at night which do you think would cool faster a black road surface or surface of a lake?
The road would cool fastest.
How does surface area affect the rate of cooling?
the color of an object will affect the rate of cooling e.g black objects cool down faster than shiny objects, the temperature around the object will also affect the rate of cooling, if the surrounding is cold, a hot object will cool faster than when the surrounding is hot.
Which will cool faster a rock cooled underground or on the surface?
A rock at the surface will cool faster than a rock underground.
What happens after 5 minutes when you pour hot water in two cans - 1 can is black and 1 can is shiny?
The water in the black can can be expected to cool down faster, due to radiation.
Why would a rock cool faster on top of the surface then underneath the surface?
'Cause it has less heat on the surface then under it.
Which will cool faster white pot or black pot of boiling water?
the white pan because black gathers heat the white pan because black gathers heat Oddly, both wrong. The black one will cool slightly quicker as black is a better radiator of infrared. Better collectors are also better emitters. The reason it won't make much difference is that both colours are similar at infrared frequencies. If one pan was coloured silver however, it would cool much slower.
Does Matte black or Matte white cool faster?
Matt white
Would a black compost tumbler heat up faster than a green one?
Yes it will heat up faster and cool down faster.

How can basalt layer cooled and solidified on the surface before the conglomerate layer was deposited?
Basalts cool faster.
Why do slightly ripe bananas coo faster when cut diagonally into smaller size?
They cool faster when cut into pieces because the surface area has been increased.
