What was happening in the atoms of the elements as they were giving off light?
When atoms are supplied with energy, their electrons become excited and may gain enough energy to jump to higher energy levels (shells). However, the electron is unstable in the higher energy level and will therefore release its acquired energy in an attempt to achieve stability. The energy is released in the form of light and the colour, which is determined by the frequency of the emission, depends upon the energy levels involved ( which shells it leaves and which shell it enters).
How do you know if two twins are identical or just fraternal twins that look a lot alike?
(Person that asked the question)-Once twins are born, and old enough to determine whether they are identical or fraternal, how do you know if they are identical, or just fraternal twins that look identical? I was just curious.
Does Increased temperature causes a molecule to vibrate?
Yes. The molecule vibrate about its equilibrium position. If the thermal energy is high enough the molecule can break free from intermolecular bonds leading to changes i physical phase (solid-->liquid-->gas)
What would happen to the supply of ATP in your cell if you did not eat enough carbohydrates How would this affect your cells?
If your ATP does not have enough carbohydrates it will not have enough energy to carry energy; its job is to carry energy around.
Animals store their excess energy in this form They can use this later on if they do not have enough energy?
fat
How do your muscles continue to get energy during high levels of activity when there is not enough energy?
The muscles continue to get enough energy during high levels of activity when there is not enough oxygen through the absorption of water. It is a good idea to drink water frequently when doing strenuous exercise.
Why does sodium vapor emit only certain frequencies of visible light?
It is because the electrons surrounding an atom, say sodium, can only exist at certain energy levels. When a photon (packet of light energy) hits an orbiting electron it only gives energy to that electron if the energy of the photon is exactly enough to move the electron to a higher energy level, if not it doesn't effect the electron. As the energy of a photon is directly proportional to the it wavelength, only certain wavelengths affect an atom's electrons. When they do effect the electrons the photon is absorbed, giving the absorption spectrum. Emission spectra are the reverse of this process, when an electron cascades back down to its lowest possible energy state after this photon interaction it gives out certain frequencies of light. The energy of this light will be equal to the energy absorbed, so the photons emitted will be equal to the photons absorbed which is why emission spectra look like the inverse of an absorption spectrum.
Why does iodine change colour when starch is present?
The startch and iodine molecule interact- the electron energy levels are affected on the iodine enough to change the absorption spectrim and hence the color.
Absorption happens when nutrients are small enough to pass into your?
Intestine
How is an emission spectrum of an element generated?
All hot solids or dense enough gases emit black body radiation. Gases that are not very dense are are cold absorb particular wavelengths while gases that are not dense but are hot produce their characteristic emission spectrum.
Which nuclear decay emission only consists of energy?
Gamma decay is primarily "energy only", in that it is the emanation of photons that represent energy. However, and this is important to understand, gamma does not exist by itself - gamma is a secondary reaction to a primary reaction that involves a change to the nucleus - a change that is usually represented by alpha or beta decay.So, with the exception of the few metastable forms of radionuclides, gamma still, ultimately, is preceded by particle emission. (Even in the metastable forms, the gamma is preceded by particle emission - its just that the event is delayed enough to "count it" as a separate event.)
How can renewable energy sources prevent global warming?
Renewable energy sources are generally carbon emission free, that is, they emit no carbon dioxide (apart from their construction). Present energy sources are mainly fossil fuels, which, when burnt, release carbon dioxide, a powerful greenhouse gas which is causing global warming. If we can switch from fossil energy to renewable energy then we have the global warming problem fixed (if we do it quickly enough).

Why do I have no energy?
You do not have energy probably because you are not taking enough carbohydrates and enough water.
Why is there so much carbon emission in US?
The EPA historically has not had enough power to enforce better emission regulations. Most of the emissions in the US, almost 50%, come from coal-burning power plants.
