Answer:

It is a fundamental concept that atomic spectra are discontinuous the electron's energy levels are quantized which is a quantum mechanics concept that a system is limited to certain energy states which depends on the particular system being refereed to

Explanation:

Atomic electrons posses only specific energy levels with nothing in between those levels, it can be excited to a higher energy level by gaining the required energy or lose energy in quantized packets to drop to a lower energy level hence the discontinuous spectral lines

GuDViN [60]

<u>Answer:</u> The phase change process in which solids gets converted to gases is sublimation.

<u>Explanation:</u>

For the given options:

<u>Option a:</u>  Condensation

It is a type of process in which phase change occurs from gaseous state to liquid state at constant temperature.

Gas\rightleftharpoons Liquid

<u>Option b:</u>  Melting

It is a type of process in which phase change occurs from solid state to liquid state at constant temperature.

Solid\rightleftharpoons Liquid

<u>Option c:</u>  Sublimation

It is a type of process in which phase change occurs from solid state to gaseous state without passing through the liquid state at constant temperature.

Solid\rightleftharpoons Gas

<u>Option d:</u>  Deposition

It is a type of process in which phase change occurs from gaseous state to solid state without passing through the liquid state at constant temperature.

Gas\rightleftharpoons Solid

Hence, the phase change process in which solids gets converted to gases is sublimation.
