What else can I help you with?
Can gases emit radiation?
Yes, gases can emit radiation. When a gas is heated, it can emit thermal radiation in the form of light. Additionally, certain gases can absorb and emit specific wavelengths of radiation, such as in the process of fluorescence or phosphorescence.
Do galaxies emit light and why?
Well, you can see them, right? - Galaxies contain millions or billions of stars; each of these stars emit light.
Is there any device which can emit smell when heated?
Yes, there are devices called scent diffusers or aroma diffusers that can emit pleasant smells when heated or when essential oils are added. These devices often use technology like ultrasonic vibrations or heat to disperse the scent throughout a room.
Would a gas room heater be convection conduction or raidiation?
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.
What are thermal emitters?
Thermal emitters are materials that emit infrared radiation when heated. They are commonly used in applications such as infrared heaters, night vision devices, and temperature sensors. Thermal emitters can be natural materials like heated metal or synthetic materials designed to emit specific wavelengths of infrared radiation.
Why do scientists think that quasars emit a large amount of energy?
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.
What would be produced when calcium is heated in air?
Calcium most likely will react with the oxygen in the air. 2Ca(s) + O2(g) -->2CaO(s). It would form solid calcium oxide.
What is the effect where an object begins to glow when it is heated?
The effect you are referring to is called incandescence. It occurs when an object, such as a filament in a light bulb, becomes hot enough to emit visible light as a result of being heated.
What will happen if Sulfur and sugar will be heated?
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
What happens when matter is heated to extreme temperatures greater than 10000 degree Celsius?
When matter is heated to extreme temperatures greater than 10,000 degrees Celsius, it typically undergoes changes such as ionization, where atoms lose their electrons, leading to the formation of a plasma state. This extreme heating can also cause matter to emit light across various wavelengths, which is often observed as a glowing or incandescent effect. Additionally, at such high temperatures, chemical bonds within the matter can break down, leading to further dissociation and recombination of atoms and molecules.
What is gold at 3000 degrees Celsius?
At 3000 degrees Celsius, gold would be in a molten state, as its melting point is 1064 degrees Celsius. In this liquid state, gold would be highly reactive and easily form alloys with other metals due to its high temperature. The intense heat would also cause the gold to emit a bright yellow-white light, similar to the color of the metal itself.
Why would the core of a star emit light and the outer atmosphere of a star absorb it?
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.
