Is dull surface a good radiator of heat?
It is in fact the best radiator. Dull black is the best absorber and emitter. Then shiny black, followed by white, then silver. While the best reflector goes the other way around (silver's the best, then white, followed by shiny black, then dull black)
What are the physical properties of metal and non-metal?
metal- shiny non-metal- dull
How much heat is needed to get a bolt out?
Quite a bit--sometimes you need to heat the thing to a dull red.
What solid does not conduct but is malleable and shiny?
t that is a malleable, shiny solid, but doesn't conduct heat or electricity
How much heat can aluminum withstand?
That depends on what you are trying to ask.First point is that heat is energy in transit - if it isn't moving from one place to another it's technically not heat. Thermal energy - the energy held by a mass due to temperature is a better term, but even that is a bit ambiguous.With that in mind...if you mean how much energy can be stored as thermal energy by aluminum, you would have to look up the heat capacity - which is approximately 0.91 kJ/kg K (the exact value depending on temperature and purity of the aluminum)If you mean how much resistance aluminum foil can provide to the transfer of heat, that would depend on the temperature gradient and how shiny the aluminum was - shiny aluminum will reflect more heat that dull/burnished aluminum surfaces.
Which reflects heat shiny black or dull black?
Shiny black
What absorbs more heat-shiny black or dull black?
Generally, dull black
Why dull black surface heats up more quickly than bright shiny surfaces?
The shinier the object, the more heat will reflect off of it. For example, a black carwill heat up much faster as the dull black will absorb the heat, while a shiny coloured car will reflect the heat molocules off.
Which would keep water hot for longer a shiny chromium jug or a dull chromium jug?
A polished finish will reflect heat back into the the jug while a dull finish will radiate more heat to the environment. The shiny jug therefore will retain heat better than the dull jug.
Why does shiny surfaces absorbe more energy then dull surfaces?
Because, shiny surfaces reflect heat, they don't emit much heat and they don't absorb much heat!
Is dull surface a good radiator of heat?
It is in fact the best radiator. Dull black is the best absorber and emitter. Then shiny black, followed by white, then silver. While the best reflector goes the other way around (silver's the best, then white, followed by shiny black, then dull black)
Why does dull dark objects emit more heat than bright shiny ones?
Dark objects absorb heat, while bright shiny ones reflect heat back.
What distinguishes nonmetals from metals?
metals are shiny and good conductors of heat and electricity. Nonmetals are dull and poor conductors of heat and electricity.
Which is the best absorber of inferared radiation heat a dull surface or a shiny one?
A dull surface will absorb infrared best, but it needs to be dull at infrared wavelengths. Do not judge the infrared behavior by the visible performance.
Why does something shiny stop heat radiation?
Types of light energy are reflected off of shiny surfaces back into the atmosphere. Other surfaces, such as darker ones, absorb the light energy and heat up much quicker.
What colour car absorbs more heat black red blue green whiteshinyb or dull surface?
black, because darker colours absorb more heat than lighter colours. I'd say that dull colours absorb more heat, as shiny colours reflect more heat and light.
Which metal can would retain more heat a silver shiny can or a black dull can after they have both been in the sun?
Black one will be in high temperture.
