What diffusion is lower concentration to a higher concentration?
If it is water moving from a higher concentration to a lower concentration, the diffusion is called osmosis.
What way is wind always moving?
From higher to lower pressure areas.
When moving from a lower energy level to a higher level does the atom give off light?
No, it is inversely.
Is simple diffusion active or passive?
Passive, it's just a substance moving from higher to lower concentrations.
Does the glowing of a neon light caused by an electron emitting energy as it is moving from lower to higher energy levels?
No, other way around. The energy difference between the higher level and the lower, appears as photon energy.
Gases move from the chemistry lab into the hall by what?
Diffusion- the random motion of gases moving from a higher concentration to a lower concentration.
What happens to a bag of potato chips when moving from lower to higher elevations?
The bag can pop open as the air inside expands.
Light given off by an atom is its what?
it is its energy emitted by electrons while moving from higher energy state to lower one.
The light produced by signs using neon gas results from electrons that are?
It is moving from a higher to a lower pricipal energy level.
Air moves from where pressure is higher to lower or lower to higher?
Higher to lower.
How can astronomers determine whether a star is moving towards or away from earth?
Astronomers determine whether a star is moving toward or away from the Earth via the Doppler effect. Imagine a motorcycle moving past you. As it drives towards you, it has a higher frequency, and a lower frequency when it drives away. The same thing happens with light. As an object moves towards us, its light has a higher frequency and lower wavelength - this is called blueshift. As an object moves away from us, its light has a lower frequency and higher wavelength - this is called redshift.
