What is the difference between a good radiator of heat and a good reflector of heat?
A good radiator of heat can absorb and release heat effectively, while a good reflector of heat can bounce heat off its surface. Radiators are designed to dissipate heat, while reflectors redirect heat away from a surface.
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.
Is shiny silvered surface is a good radiator of heat?
Yes, a shiny silver surface is a good radiator of heat because it has high reflectivity, which means it can reflect thermal radiation effectively. However, the ability to radiate heat also depends on factors such as surface area and the surrounding environment.
Is dull black surface is a good radiator of heat?
A dull black surface is a good radiator of heat because it has a high emissivity, which means it can efficiently emit thermal radiation. This is why black surfaces are commonly used for radiators and heat exchangers to improve heat transfer.
Is the earth a good absorber and good radiator of heat?
Yes, the Earth is a good absorber of heat, with its atmosphere and surface absorbing solar radiation. It also radiates heat back into space in the form of infrared radiation, making it a good radiator of heat. This process is essential for maintaining Earth's energy balance and regulating its temperature.
What surface are bad radiator of heat?
white

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)

Is green coloured surface good radiator of heat?
Green surfaces are not inherently good radiators of heat. The ability of a surface to radiate heat depends on factors such as its material, texture, and emissivity. Green surfaces may absorb and retain heat differently depending on these factors.
Is marble a good radiator reflect-er or ab-sorer?
Marble is neither a good radiator reflector nor a good absorber. It has poor thermal conductivity and will not efficiently reflect or absorb heat. Materials with higher thermal conductivity, such as metals, are better suited for these purposes.
Why is there a shiny surface at the back of the radiator?
The shiny surface is a reflector, to reflect the heat outwards towards you.
What heat transfer that is warming hand over a radiator?
Conduction is the heat transfer process that warms your hand when placed over a radiator. The radiator transfers heat to your hand through direct contact, as the molecules of your hand gain kinetic energy from the warm radiator surface.
Why does a radiator lose heat easily?
Lots of surface area - its designed that way.
