Question

Which unit cell is represented by the figure? (A) simple cubic (B) simple hexagonal (C) body-centered cubic (D) face-centered cubic At constant temperature, an increase in volume of a gas results in a decrease in gas pressure. According to the kinetic molecular theory, what is the reason for this phenomenon? (A) The individual collisions overall are less energetic at larger volumes. (B) Collisions with the walls of the container per unit area per unit time decrease. (C) Both (A) and (B) contribute to the decreased pressure. (D) Neither (A) nor (B) contributes to the decreased pressure. Under what conditions is the solubility of carbon dioxide in water greatest? (A) low temperature and high pressure (B) low temperature and low pressure (C) high temperature and low pressure D) high temperature and high pressure

Explanation / Answer

Q31.

From the cube

you can see there is always a centered paritle in each side/face

therefore

this is a FACE-CENTERED CUBIC
