Water drops that fall when the temperature is below freezing fall as?
Water drops that fall when the temperature is below freezing, fall as SNOW . Water drops that fall when the temperature is above freezing fall as RAIN .
What acid burns green in a Bunsen burner?
Boric Acid! When boron is heated, electrons absorb a certain amount of heat energy that causes them to jump to higher energy levels. After While, these electrons lose their energy and fall back down to their original levels, and as they do so, they emit energy in the form of light. Because the energy absorbed by electrons is different per element, each element will give a different color. Boron gives off a green color.
When you put an element in a flame you see different colors of light given off How why?
The heat of the flame provides thermal energy which can excite the electrons in the atom to higher energy levels. When the electrons 'relax' down to their ground state the excess energy is given out as radiation. For it to be coloured, the radiation must fall in the visible spectrum.
What is the meaning of a hole in the ozone layer?
See "What is the ozone hole?" in the "Related questions" section below.
What is givin off when electrons in an atom fall to a lower orbit?
Energy (in the form of photons) is given off when electrons in an atom fall to a lower energy level.
Energy produced by the rise and fall of ocean levels is an?
Energy produced by the rise and fall of ocean levels is tidal energy. Tidal energy is a renewable source of energy that scientists have found ways to use for energy supply required around the world.
If you heat a gas so that collisions are continually bumping electrons to higher energy levels when the electrons fall back to lower energy levels what does the gas produce?
energy an emission line spectrum
When the electrons of an excited atom fall back to lower levels there is an emission of energy that produces what?
The electrons emit photons of light equal in energy to the energy that was absorbed.
Why do atoms give off light when they drop energy levels in an atom?
When electrons fall to a lower energy level, they give off energy in the form of light.
An atom is in an excited state when it has its lowest energy?
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
Why don't the elements in your bodies add up to 100 percent?
Because some elements present in the body are at such low levels they fall below detection limits. Typical instrumentation has limits to what concentrations they can detect.
What do atoms do when electrons move energy levels?
Atoms don't do anything. If the electrons go to a higher energy state, they use energy. If they fall back to a lower state, they release energy. This shouldn't affect the entire atom, just the electrons.
Example of gravitational potential energy?
Any object that is above the chosen reference level (often this is the ground level) will have positive potential energy. Any object below the chosen reference level will have negative potential energy.
Comparing energy levels of electrons with an electron's orbital?
As electrons move out of the valence shell into higher orbits they have energy to release. As they fall back down, giving off a photon, they tell the quantity of energy released by the color they give off.
How does the energy available in plants affect the timing of the farmers harvest of their grain crop?
Crops are harvested to provide energy for various sources but usually as a foodstuff for humans or animals. As crops grow and develop the amount of energy stored in the crop also increases and the farmer has to judge when the levels of energy stored is at its likely maximum level as this will be the optimum time to harvest. If allowed to grow too long the crop starts to use its own energy reserves to develop seeds etc and energy levels start to fall and if not allowed to mature enough before harvest then levels of energy may be lower then expected when harvested.
Water drops that fall when the temperature is below freezing fall as?
Water drops that fall when the temperature is below freezing, fall as SNOW . Water drops that fall when the temperature is above freezing fall as RAIN .
Can regular swimming cause hair fall due to chlorine..what are the safe levels for chlorine in pools?
You can check the pool chlorine levels with some litmus paper the levels need to be between 7.2 and 7.6 on the ph scale it would need a lot of chlorine for hair to fall out Safe levels are below 5ppm chlorine. You won't die if you swim in 10 ppm once or twice, but there could be harmful effects if you swim very regularly in high doses.
