Which method would increase the solubility of a gas?
increasing the pressure
stirring the solvent quickly
increasing the temperature
decreasing the amount of solvent

Temperature and Pressure One way to increase the solubility of a gas is to decrease the temperature of the liquid.  The solubility of a gas in a liquid is usually temperature dependent, although it depends on the particular combination of which gas and which liquid.  Usually the solubility of a gas goes down with increasing temperature (think of warm carbonated beverages going flat). 

The other way to increase the solubility is to increase the pressure of the gas.  The higher the pressure of the gas above the liquid, the more will dissolve.  Again, think of a carbonated beverage:  when it is sealed it doesn't go flat because it is under pressure, but when open to air, it will go flat. 

Of course: ) what’s your name ?
