How do you know if a reaction will increase entropy?
How do you know if a reaction will increase entropy? Therefore, if the reaction involves only gases, the entropy is related to the total number of moles on either side of the reaction. A decrease in the number of moles on the product side means lower entropy. An increase in the number of moles on […]

How does Doppler effect prove the universe is expanding?
How does Doppler effect prove the universe is expanding? Edwin Hubble used the Doppler effect to determine that the universe is expanding. Hubble found that the light from distant galaxies was shifted toward lower frequencies, to the red end of the spectrum. If the galaxies were moving toward Hubble, the light would have been blue-shifted. […]
