Is the good radiator of heat a shiny silvered surface or white surface?
A shiny silvered surface is generally better at radiating heat compared to a white surface. The reflective nature of silver helps to minimize heat absorption, allowing it to emit more thermal radiation and cool down faster.
Why does black cool quickest?
black cools quickest because the heat goes straight through it but white reflects so if you had two really thick sheets of metal one Matt black and the other shiny white put heat on them then cut them in half, the middle of the black one will be hot but the middle of the white one won't because the heat is going through the black
Why is white and shiny surface suitable for fridge-freezer?
A white and shiny surface is suitable for a fridge-freezer because it helps to reflect light and heat, which can improve the energy efficiency of the appliance. The white color also helps to keep the exterior surface of the fridge-freezer cool by reflecting sunlight, thus reducing the workload on the cooling system. Additionally, the shiny surface makes it easier to clean and maintain the appearance of the fridge-freezer.
Why is a white and shiny outside surface suitable for a fridge freezer?
A white and shiny outside surface is suitable for a fridge freezer because it helps to reflect heat rather than absorb it, making it easier for the appliance to maintain a cool temperature. The reflective surface can also make it easier to clean and maintain the appearance of the fridge freezer.
How do you cool down hot metal faster?
To cool down hot metal faster, you can use methods such as quenching in water, oil, or air. This rapid cooling can help increase the hardness and strength of the metal. Additionally, placing the hot metal in contact with a cool surface can also help speed up the cooling process.
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.
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.
Is the good radiator of heat a shiny silvered surface or white surface?
A shiny silvered surface is generally better at radiating heat compared to a white surface. The reflective nature of silver helps to minimize heat absorption, allowing it to emit more thermal radiation and cool down faster.
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.
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 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
Why does black cool quickest?
black cools quickest because the heat goes straight through it but white reflects so if you had two really thick sheets of metal one Matt black and the other shiny white put heat on them then cut them in half, the middle of the black one will be hot but the middle of the white one won't because the heat is going through the black
Would a black compost tumbler heat up faster than a green one?
Yes it will heat up faster and cool down faster.
