How do crystal systems differ from eachother

Answers

A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice.
Crystal are classified according to the possible relations of the crystal axes.This classification is called as crystal system.

An increase in the temperature of a contained liquid__

D)Causes the vapor pressure above the liquid to increase

Water could be made to boil at 105C° instead of 100C° by __

B) increasing the external pressure

How do crystal systems differ?

C) in angles between bases in the number of edges of equal links

Hope this answers your question!

Explanation:   An increase in the temperature of a contained liquid- will  D)Causes the vapor pressure above the liquid to increase

Because when the temperature in increased , it will increase the kinetic energy of the molecules and would not cause the vapor pressure above the liquid to decrease. And when temperature increases, this will cause more particles to escape from the surface of the liquid.

Water could be made to boil at 105C° instead of 100C° by -  B) increasing the external pressure

As decreasing the external pressure and taking the sample to a higher altitude wont affect the boiling rates of water.
