81 times more energy. 3 to the fourth power...so it would be 3 x 3 x 3 x 3 =81
All objects emit (give out) and absorb (take in) thermal radiation, which is also called infrared radiation. The hotter an object is, the more infrared radiation it emits. However; the hotter an object, the faster it will emit infrared radiation. Even though hotter objects can absorb infrared radiation, they will continue to emit infrared radiation much faster than they absorb it from any colder objects / sources around them, until an equilibrium is achieved with the objects surroundings i.e. it is always an antagonistic relationship with the objects surroundings and the surroundings with the object.
Generally, yes. For example, a hot coil may emit infrared or even red light, and hot iron glows. When cool, however, they do not emit light. The reason is that electrons are given more energy from the heat, so they raise in their location from the atom, and when they return to a stable location they give off light.
luminous objects allows to absorb ans emits light.
That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.That is because every object emits electromagnetic radiation, according to its temperature.
it emits very high energy photons
Any object emits infrared radiation. The hotter the object, the more infrared is emitted.

The temperature of the radiating body determines the intensity and characteristics of the radiation it emits. Two electromagnetic radiation principles describe the relationship between a radiating body�s temperature and the radiation it emits. 1. Stefan-Boltzmann�s Law: Hotter objects emit more total energy per unit area than colder objects. 2. Wein�s Displacement Law: The hotter the radiating body, the shorter the wavelength of maximum radiation.

Radiant energy is a term that is almost exclusively used for electromagnetic energy. When something is hot, it emits radiant energy. The sun is an obvious example, but all object actually emit radiant energy. The hotter the object, the more energy. Sound does carry energy, but it is not electromagnetic. Objects can emit sound and even "radiate" sound, but the term radiant energy is not normally used for sound.
The best example of a large object in the solar system that emits electromagnetic waves is the sun, since it is the largest such object and also emits the greatest amount of electromagnetic waves. But also note, the planets Earth and Jupiter also both qualify as large objects which emit electromagnetic waves.
The hotter the object the more it radiates. The blacker the surface the more it radiates. The surrounds only affect the total loss of heat from the object, not the actual rate the object emits thermal radiation. From my imperfect memory I seem to recall that the rate an object looses heat by radiation to its environment is proportional to the forth power of the difference in temperature between the object and the environment.
it emits very high energy photons
No, why should it. An object that emits heat cools down. No energy is created or destroyed.
An object at any temperature emits electromagnetic radiation, mainly from its surface. This can be infrared, or - at higher temperatures - visible light. This electromagnetic radiation can travel through empty space, or through air. If it strikes another object, the energy (or part of the energy) will be transfered to this other object.
