A gas heated to millions of degrees would emit X-rays.
a resistor
Well, you can see them, right? - Galaxies contain millions or billions of stars; each of these stars emit light.
That would depend upon whether the greenhouse is in use, and whether it is being heated, and how. Greenhouses heated with propane will release CO2. Greenhouses not in use may emit various gases, depending upon the state of decomposition of any organic material contained within them. In general, an unheated (or solar heated) greenhouse in use will tend to emit oxygen, via photosynthesis activity of the plants contained within it.
Definitely not! Galvanized when heated will emit toxic fumes.
it would emit heat in the form of radiation. It will also heat the air which will cause convection. However, these heated gasses will be vented out of the flue so as not to contaminate the air in the room.
Scientists think that quasars emit a large amount of energy because they believe each quasar has an incredibly large black hole in the center of it. They believe a torus, or disk of dust and gas, has material that falls near the black hole causing it to hear to millions of degrees that accelerates the reaction outward.
When a substance is heated up, it emit heat radiation. In such way substance keep on losing heat energy. Thus a way that increase heat losing can lower heat of substance. Water can used as heat absorber.
If heated in open air it will react with atmospheric Oxygen according to the following reactionsSurfer will emit Sulfur dioxide gas S(s) + O2(g) → SO2(g)sugar will emit carbon dioxide gas and water vapour2C6H12O6(s) + 3O2(g) → 12CO2(g) + 12H2O(g)-vapour
In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels. When they fall back, they emit light.In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels.

The core would emit light because it is hot. The outer atmosphere would absorb light because it is not completely transparent. It would also re-emit radiation itself, because of its heat.
The wave model of light can not explain why heated objects emit only certain frequencies of light at a given temperature, why some metals emit electrons when light of a certain frequency is shone upon them, and it cannot explain the emission of different wavelengths from the different colors when an object (iron for example) is heated
They're hot (above about 800 degrees Kelvin).
