Is dull black surface is a good radiator of heat?
Yes, it is. As dull and black surfaces are the best emitters as well as the best absorbers of radiation. Hope my answer is good enough to be stand up your question needs.
What are the two ways of radiation?
two ways of radiation are the sun because its heat travels in electromagnetic waves and radiates the earth and an electric radiator because it heat will radiate whatever it is heating just like the sun will
Which color is the best absorber and emmiter of heat?
Dull black is the best heat radiator.
An object that is a good radiator of electromagnetic waves is also a good?
An object that is a good radiator of electromagnetic waves is also a good source of energy (heat,light ...)
Describe a convection in a room heated by a radiator?
it hotter
In general good absorbers of electromagnetic radiation are also good?
Yes, Good absorber of heat are good emitters of heat. And in both the way rate is same. This is Kirchoff's Law.
Why car radiators are black?
Objects that are black in color are the most efficient emitters/absorbers of electromagnetic radiation. Heat is infrared (IR) electromagnetic radiation. If the black object is hotter than its surroundings (which a car radiator usually is) it acts as an emitter, if the black object is cooler than its surroundings it acts as an absorber. Thus a hot car radiator that is black will emit IR heat radiation more efficiently than ti would if it was any other color. Thus it will help keep the engine from overheating better than a radiator of any other color.
Is it true that energy from the sun reaches earth through electromagnetic waves?
Electromagnetic radiation (EMR) is strange. It is like waves in some ways, and it is like particles in some ways. EMR includes all light and radio waves, and other categories as well. One of the properties of EMR is that it does not need a 'medium' to move through. It can easily travel through vacuum. Other kinds of wave need a physical medium through which to propagate. So EMR of a wide range of frequencies is coming toward us from all points of the sky, traveling through the vacuum of space until it is absorbed by particles in space, in our atmosphere, or at the surface.
What happens to a blackbody radiator as it increases in temperature?
It gives off a range of electromagnetic radiation of shorter wavelengths.
What type of radiator of energy is an object that is a good absorber of radiation?
An object that absorbs heat well will also emit heat well. The object will emit heat until equilibrium is reached with its surroundings.

What is a better absorber and radiator of heat energy soil or water?
Water absorbs and radiates heat better than soil does.
What will help you remember the word radiation?
Remember the word 'Radiator' and you'll probobly remember Radiation. :)
Where is the radiation drain for mustang gt 2004?
The radiator drain is on the bottom of the radiator. It is a small petcock valve.
