When an electron jumps from an orbit where n = 4 to one where n=2, photon is absorbed. o true o false

False

Explanation:

This statement is negates the photoelectric effect.

When an electron absorbs energy it jumps from a lower shell to a higher shell. When the electron releases energy it jumps from a higher shell to a lower shell.

The Kinetic energy of an ejected electron is

Where,

h = Planck's Constant

f = Frequency of incident photon

= Work function

So, this statement is false.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

conduction, convection, radiation
