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.

An object is warmer than its surroundings it will?
Release its heat energy until the object (system) and the surroundings are the same temperature.
What determines whether an object is a net absorber or a net emitter of radiant energy at a given time?
All substances above absolute zero emit radiant energy. Whether the object emits more than it absorbs depends on its temperature compared to the temperature of its surroundings. An object warmer than its surroundings will usually be a net emitter.
What types of objects emit of infrared raditation?
Any object emits infrared radiation. The hotter the object, the more infrared is emitted.
As the temperature of an object rises so does the?
as the temperature of an object rises so does the.
What sitting still at the top of a slope has what type of energy?
An object that is stationary and at the top of something has "potential energy". (If you're getting into equations, it's PE = mgh, where PE = potential energy, m = mass of the object, g = the force of gravity, and h = the height of the object.)
An object is a good emitter of radiation if it is what?
An object is a good emitter of radiation if it is a good absorber of radiation.
What kind of surface should an object have to be a poor absorber of radiation?
A reflective one
Why are carbon dioxide and water vapor called selective absorbers?
Any object that can specifically absorb and emit radiation (in the form of, say, infrared radiation), is called a selective absorbers. An example is: Snow. It is a good absorber of infrared radiation but poor absorber of sunligh. Object that selectively absorb radiation at some wavelength tend to radiate radiation at that same wavelength. CO2 and water vapors are both very good absorber of infrared radiation but at the same time poor absorber of different forms of solar radiation that are visible to us.
What determines whether an object is a net emitter or a net absorber of radiant energy?
magic
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.
Experiment to show that a dark surface is a ggod absorber of radiation while a white surface is a bad absorber of radiation?
Paint two otherwise identical objects, one with white paint, the other with black paint. Put both of them in the sunshine. The black object should get hot faster than the white one, because the absorbed heat energy gets converted to heat.
If heat energy is tranferred away from an object what will the object feel?
radiation
Is radiation a measure of the average kineic energy of the particles in an object?
No, radiation is not a measure of the average kinetic energy of particles in an object. Radiation refers to the emission of energy as electromagnetic waves or particles from a source. The energy of radiation can vary depending on the type and source, and it is not directly related to the average kinetic energy of particles in an object.
Will an object will be a net radiator of energy when its thermal energy is less than that of its surroundings?
No, an object will not be a net radiator of energy when its thermal energy is less than that of its surroundings. In this case, the object will instead absorb thermal energy from its surroundings in an attempt to reach thermal equilibrium.
An object will normally be a net radiator of energy when its temperature is?
A radiator is a type of heating device. An object will normally be a net radiator of energy when it's temperature is higher than its surroundings.
How does energy travel to Earth?
There are three types of transferrable energy: conduction, convection, and radiation. Conduction- heat that moves from solid object to solid object by physical means. Convection- heat that moves about a gaseous object (think about boiling water) Radiation- light energy that can travel through space and needs no object to transfer through. The correct answer for this question would be radiation.
An object is warmer than its surroundings it will?
Release its heat energy until the object (system) and the surroundings are the same temperature.
