yes. as long at the obj is above absolute 0, it has energy and hence will emit heat.
whether there is a net heat gain or loss depends on the environment it is in. yes. as long at the obj is above absolute 0, it has energy and hence will emit heat.

To be a bit more specific, if by radiation you mean electromagnetic radiation, then only objects which contain some electrical charge can absorb radiation. Since all atoms contain electrically charged elementary particles, the objects that we normally encounter in our lives can absorb radiation. There are, however, some objects in the universe which are devoid of electrical charge, such as the neutrino; it does not absorb radiation.
No, because heat implies that a transfer has occured between two objects.
no .. unstable nuclei which undergo radioactive decay emit gamma rays.
Infra Red radiation which is a type of Electromagnetic radiation.
Only those with temperatures above absolute zero.
thermal radiation
yes
no...
Yes, it still has some amount of internal energy or "heat". Even considering the coldest objects in the universe, it is still impossible for an object to have no heat, and this theoretical state is known as absolute zero.
Heat doesn't travel through a vacuum. The energy could be changed to light and radiate across the gap, so that would be radiation.
Electromagnetic radiation.
Her face seemed to radiate kindness. Spokes radiate from an axle.
There are three mechanisms by which thermal energy (heat) is transferred through space: conduction, convection, and radiation.1Radiation is the transfer of heat energy through empty space. All objects with a temperature above absolute zero radiate energy at a rate equal to their emissivity multiplied by the rate at which energy would radiate from them if they were a black body. No medium is necessary for radiation to occur; radiation works even in and through a perfect vacuum. The energy from the Sun travels through the vacuum of space before warming the earth. Also, the only way that energy can leave earth is by being radiated to space.The transfer of thermal energy through space is called Radiation
All objects radiate energy at a rate depending on their temperature.
yes
no...
Yes
x rays
Styrofoam
It is because stars and other cosmic objects, radiate energy across the whole of the electromagnetic spectrum.
YES
At abosolute 0 or -273K
Yes, a drum set can radiate sound energy when the surface of the drum vibrates on striking it to set particle molecules in air to transfer energy in a wave form and radiate out.
Yes, all objects radiate some heat BUT the hotter the object, the more heat it radiates!! radiation its self is not hot but when it is absorbed by an object its particles in the object move more rapidly thus heating it
radiate energy
