Question

Conversion of gas to liquid is called as:
A. Sublimation
B. Condensation
C. Evaporation
D. Deposition
E. Melting

Answer 1

Hint: Condensation is the joining of things together or can be considered as the patch up. Condensation process is also known as dehydration in which there is the removal of water.

Complete step by step solution:

Dehydration consists of 2 words (de) means to remove and (hydrate) means water. So in this process of condensation the complex and large molecules are produced from the smaller molecules when the removal of water takes place. Further the macromolecules are produced by these condensation reactions.
Examples: of Carbohydrates, proteins, lipids, nucleic acid, etc. In this process some specific enzymes are involved mostly they are used in the synthesis of the molecule as well as for starting the reaction we need some energy which is the activation energy in the form of ATP. Whereas in sublimation a phase transition occurs which is the change in the matters state that is getting converted to another form. In sublimation a solid particle changes to a gaseous particle without even getting changed to the liquid state dry ice, solid $C{O_2}$ are the examples of sublimation. In evaporation the vaporization occurs at the liquid surface when it gets changed into the gaseous phase it is not necessary that the surrounding gas has to be saturated. When the liquid particles collide with one another they get their energy transfer to each other on the basis of their collision. Talking about the position it is the settling down of a solution. Deposition is a reverse process of dissolution. Deposition can also be described as the change in phase of a gas to a solid without getting into liquid face and also sometimes known as Re-sublimation.

The correct answer is B.

Note: Melting commonly known as fusion which is a process of phase transition of a solid particle to the liquid state. Which only takes place when the solid's internal energy is increased mostly by applying some heat and pressure which tend to increase the melting point of the substance.
