marysya [2.9K]

Answer:

a) Solubility diminishes.

b) Solubility remains constant.

c) Solubility increases.

d) Solubility increases.

Explanation:

Hello,

a) In this case, we've got to take into account that the solubility of a gas into a liquid increases as the pressure does it (because the molecules are forced to gather with the liquid's particles) and the other way around, in such a way, as the pressure is decreased, the solubility is decreased as well.

b) Well, the outer space is related with the atmospheric pressure as long as the column of air is what is exerting the pressure, thus, as this pressure is quantified as 1 atm, there won't be any appreciable change in the solubility as the pressure remains the same.

c) Now, as the pressure is increased, the solubility is increased in a very similar way that in the a) part.

d) Submerging the solution 40m underwater means that the fluid's column above the solution is increased, thus, the pressure is increased, so the solubility is increased as well.

Best regards.

Which statement about atmospheric pressure is false?
Vinil7 [7]

Answer:

D) With an increase in altitude, atmospheric pressure increases as well.

Explanation:

Generally when altitude increases, the value of pressure decreases. This shows that pressure is inversely proportional to altitude. For example, the higher the altitude, the lower the pressure and vice versa. At very high altitude, the number of molecules of air are smaller than the number of moles of air at very low altitude. Thus, the higher the altitude, the lower the atmospheric pressure and the lower the altitude, the higher the atmospheric pressure. Therefore, option (D) is false.
