How does quantum theory explain the emission spectra of atoms? a. electrons absorb the energy they need to jump to a higher energy level from any light source. b. a single, specific amount of energy is associated with each movement of an electron between energy levels. c. electrons gain and release energy in a slow, continuous fashion. d. the movement of an electron between energy levels occurs gradually as small amounts of energy are absorbed.

B.A single, specific amount of energy is associated with each movement of an electron between energy levels.

Explanation:

As we know by the Bohr's theory that total energy of an electron in a given energy state is given by

now here if we will find the change in energy of two states then it is given by

now when this specific amount of energy is absorbed by the electron then only it will change the state of energy.

so here correct answer will be

B.A single, specific amount of energy is associated with each movement of an electron between energy levels.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the
