What happens to the pressure of a gas inside a rigid container if the temperature of a gas decreases?
NikAS [45]

Answer:

If the temperature of gas is decreased the pressure will also goes to decrease.

Explanation:

The pressure and temperature have direct relation. If the temperature of gas will increase the pressure of gas will also goes to increase.

According to the Gay-Lussas's Law,

The pressure of given amount of gas is directly proportional to the absolute  temperature when volume is kept constant.

Mathematical relationship:

P ∝ T

P = kT

P/T = k

and

P₁/T₁ = P₂/T₂

Hydrogen chloride gas is dissolved in water to produce a solution of hydrochloric acid.
asambeis [7]

Answer:

Water is a polar solvent

Explanation:

We must know that pure dry hydrogen chloride gas does not show any acidic property.

In fact, when hydrogen chloride is dissolved in water, it breaks up into H3O^+ ions and Cl^- ions. This is possible because water is a polar solvent and assists the ionization of HCl.

In nonpolar solvents such as benzene, hydrogen chloride gas is not ionized hence it does not show any acidic property in a benzene solution.

Which of the three substances has the greatest porosity?
MArishka [77]
<h2>Answer:</h2>

<u>Most porous is gravel</u>

<h2>Explanation:</h2>

Porosity tells us how much water rock or soil can retain. It tells us about the spaces among the grains. Gravel is more bigger than sand or silt. Its grains are arranged in such a manner that their integral spaces are very bigger so they are more porous. Clay is the most porous but since it is not mentioned in the option so after clay comes the gravel. Usually gravel and sand has equal porosity.
