Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is vaporization?
A
a gas becoming a liquid
B
a liquid becoming a solid
C
a gas becoming a solid
D
a liquid becoming a gas
Explanation: 

Detailed explanation-1: -vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling. Direct conversion from solid to vapour is called sublimation.

Detailed explanation-2: -Whenever a liquid turns into a gas, the particles absorb heat energy and begin to vibrate faster, increasing the separation between them. Intermolecular interactions weaken as a result of continual vibration, and molecules begin to move apart and transform into gas.

Detailed explanation-3: -Vaporization can be defined as the process in which the liquid state changes into the vapour state. As a result of an increase in temperature, the kinetic energy of the molecules increases.

Detailed explanation-4: -There exists two types of vaporization: evaporation and boiling. Evaporation is a surface phenomenon and only occurs on the phase boundary between the liquid and the gaseous phase. The surface atoms or molecules gains energy from surroundings and overcome the attractions of other molecules and get vaporized.

Detailed explanation-5: -The vaporization (or evaporation) term typically refers to changing the state into vapor phase below boiling temperature of a liquid. However, the term can also indicate the operation of eliminating a solvent, regardless the temperature utilized (e.g., by distillation under vacuum and centrifugal force).
