When electrons are raised to a higher energy level they?
the dense of that element get lower when changing phrase
What happens to the movement molecules when their temperature is raised?
They begin to move faster. The increased temperature increases the energy of the molecule.
Why do exited hydrogen atoms emit a light spectrum that consists of a few lines rather than a continuous spectrum?
All elements do this. The emitted light is a result of electrons that have been excited (raised to a higher energy level) falling back to their minimimum energy condition (the ground state) or to any lower available energy state. All of the energy states in an atom are quantized - that is, there are only certain acceptable energy levels at which the electrons can exist. and the energy levels of these states are unique for each element. a simple way of thinking about tis is that the different energy levels are dependent on how many protons and neutrons are in the nucleus. Thus each element (in fact each different isotope) will emit a characteristic 'spectrum' or group of narrowly defined energy emissions as the excited electrons fall back to lower energy levels. these are called spectrial 'lines' because they actually appear as narrow bright lines when the light from the excited element is diffracted by a prism, as opposed to a continuous spectrum (not individual well defined lines) that you would see if you put the light from say, a white hot piece of metal, through a prism. The typical way to excite a gas like hydrogen is put it in a tube and send electricity through it. The electric discharge constantly is bumping electrons up to higher energy levels - in fact sometimes ripping them off the atom completely, so electrons are also constantly falling back to the ground state or lower eneergy states. Note also that pure gasses also only ABSORB energy on these discrete levels, so if you shine a continuous spectrum light like from an incandescent light bulb through a pure gas and then diffract the result throgh a prism, you will see dark bands corresponding to the light bands that you would see if you excited the same gas. From this the early physicists inferred a lot about the structure of the miniscule atoms which cannot be seen in any way by the human eye - only their interactions like this can be detected.
What is the source of potentail energy?
Let's take an example: gravitational potential energy. An object has more potential energy if it is raised to a higher position. The energy comes from whatever raised it up, although it is also possible (as in the case of meteorites) that the object was never on the ground in the first place.Let's take an example: gravitational potential energy.

Wehen you stir a cup of coffee what happens to the energy transferred by the coffee?
When you stir a cup of coffee, the energy of the coffee is initially raised from the bottom of the cup. This can causeÊthat hot coffee to cool quicker, but it depends on the temperature of the cup and the coffee's surface.
What happens chemically when chlorophyll absorbs light energy?
When chlorophyll absorbs light, much of the energy is transferred directly to electrons in the chlorophyll molecule, raising the energy levels of these electrons. These high-energy electrons make photosynthesis work
When sunlight excites electrons in the chlorophyll how do the electrons changes?
As red and blue light energy is absorbed by Chlorophyll electrons in outer shell are excited & raised to a higher energy level.

How is eletrical energy converted in light energy?
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.

What happens to the volume of a gas when its temperature is raised and its pressure is cept constant?
Expands because there's more energy for movement.
The line emission spectrum of an atom is caused by the energies released when electrons?
The line emission spectrum of an atom is caused by the energies released when electrons fall from high energy level. It goes down to a low energy level and the extra energy it had from higher level is released as light.
