# Does a gas dissolve in a liquid most rapidly when under low pressure?

## Does a gas dissolve in a liquid most rapidly when under low pressure?

A gas dissolves faster in a liquid if the temperature of the liquid is (increased, decreased). A gas’s solubility is faster in a liquid when under (high, low) pressure. By stirring a gas in a liquid, its solubility (speeds up, slows down) the dissolving process.

## Does gas dissolve better in high or low pressure?

External pressure has very little effect on the solubility of liquids and solids. In contrast, the solubility of gases increases as the partial pressure of the gas above a solution increases.

When a gas is dissolved in a liquid the gas dissolves faster is the liquid is?

study guide for the last test

a gases solubility is faster in a liquid when ender ___ pressure high
by stiring a gas in a liquid its solubility___ the dissolving process slows down

When a gas is dissolved into a liquid What happens when the pressure increases?

The solubility is a measure of the concentration of the dissolved gas particles in the liquid and is a function of the gas pressure. As you increase the pressure of a gas, the collision frequency increases and thus the solubility goes up, as you decrease the pressure, the solubility goes down..

### How does gas solubility depend on pressure quizlet?

The solubility of a gas increases with increasing pressure and decreases with decreasing pressure.

### What happens to the solubility of a gas in a liquid if the partial pressure of the gas above the liquid decreases *?

Pressure has very little effect on the solubility of solids or liquids, but has a significant effect on the solubility of gases. Gas solubility increases as the partial pressure of a gas above the liquid increases. Thus the solubility increases as the pressure increases.

Are gases more soluble at higher pressures?

Henry’s law has important applications. The higher the pressure above a liquid, the more gas that can be dissolved in that liquid, to a limit of course. The solubility of gases depends on the pressure: an increase in pressure increases solubility, whereas a decrease in pressure decreases solubility.

What is the effect of pressure on the solubility of gas in a liquid What is the effect of temperature?

An increase in pressure and an increase in temperature in this reaction results in greater solubility. An increase in pressure results in more gas particles entering the liquid in order to decrease the partial pressure. Therefore, the solubility would increase.

## What is an example of a gas dissolved in a liquid?

Gases dissolve in liquids to form solutions. This dissolution is an equilibrium process for which an equilibrium constant can be written. For example, the equilibrium between oxygen gas and dissolved oxygen in water is O2(aq) <=> O2(g).

## Which of the following will speed up the dissolving of a solid in water?

Stirring
Increase the temperature of the solvent. In the above example, if you heat the water up the sugar will dissolve in it faster. Stirring will also speed up the rate of dissolving a solid solute in a liquid solvent.

Which of the following will dissolve most rapidly?

Cards

Term A substance whose water solution is a good conductor of electricity is a Electrolyte or nonpolar substance Definition Electrolyte
Term Which of the following will dissolve most rapidly? sugar cubes in cold water or powdered sugar in hot water Definition Powdered sugar in hot water

How is the solubility of a gas related to the pressure?

Gas Pressure and Solubility: Gases as might be expected, increase in solubility with an increase in pressure. Henry’s Law states that: The solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.

### How is the number of gas molecules dissolved in solution increased?

The number of gas molecules dissolved in solution has increased as shown in the graphic on the left. Carbonated beverages provide the best example of this phenomena. All carbonated beverages are bottled under pressure to increase the carbon dioxide dissolved in solution.

### Which is the best definition of gases under pressure?

Gases under pressure are gases which are contained in a receptacle at a pressure of 200 kPa (29 psi) (gauge) or more, or which are liquefied or liquefied and refrigerated. They comprise compressed gases, liquefied gases, dissolved gases and refrigerated liquefied gases.

How is the solubility of solutes dependent on temperature?

The solubility of solutes is dependent on temperature. When a solid dissolves in a liquid, a change in the physical state of the solid analogous to melting takes place. Heat is required to break the bonds holding the molecules in the solid together.
