The quickest way is to heat it up. You'd want a thermometer to help validate that gases are leaving the water and it isn't boiling (just check that the temperature is below 100oC), but if you see bubbles at those lower temperatures, it's air.
Alternatively, just leave a glass of water out for about an hour. Those bubbles you see on the inside of the glass were dissolved air.

Why does humidity increase chances of rain?
It means that there is more water vapour that has been absorbed into the air. If this air then hits cooler air, it will rise and form rain clouds as the water condenses out. The cooler air cannot hold as much water vapour as the warmer humid air.
Does air float on water?
Water has a higher density than air. Anything that is less dense will float. The tube's covering is not enough to make it sink when filled with air. That is also the reason that oil and water don't mix.
Does the dragonfish breathe water or air?
The dragon fish breaths in air from the water so keep the tank well filtered, or have air bubbles.
When sound waves travel from air to water what will happen to the speed at which they are traveling?
Sound speeds up when it goes into water from air. Sound travels much faster in water than in air.
The amount of water vapor in the air is called what.?
Humidity is the measurement of the amount of water vapour in the air.
What substances in creases the number of H3O when dissloved in water?
An acid (containing dissociable H+ ions
How do you dissloved polar solvents?
polar solvents dissolved in water most of times ,and methnol,acetonitrile
What are the Dissolved gasses that are in oceans?
The three major gasses dissloved in ocean water are nitrogen, oxygen and carbon dioxide.
When iodine dissloved in alcohol the alcohol is the?
Solvent
What is difference between leak down test with water or air?
Water, with surface tension and higher viscosity than air, will not show the smallest leaks air will show. For very sensitive testing, helium is also used. Water, with surface tension and higher viscosity than air, will not show the smallest leaks air will show. For very sensitive testing, helium is also used.
How can the legislative council of a state be dissolved?
it can be dissloved by the legislative assembly of the concerned state.
When sodium is dissloved in water why fire starts burning?
Sodium is a very reactive element so when it reacts with water there is a large amount of energy released and hydrogen gas. The heat energy can ignite the hydrogen and that forms a flame.
what tools show how air temperature affects the rate of evaporation of water?
thermometer
How will you show that water vapour are present in air explain with help of diagram?
Point to a cloud. Say, "That's made of the water that's in the air." If they don't believe you, wait for it to rain. Then tell them, "That's made of water that was in the air."
Why the normal pH of rainwater is acidic?
Rainwater is normally acidic because the carbon dioxide in the air which mixes with rainwater to form weak acid. That's why its acidic ^_^ Rainwater is also because of the pollutions in the air and it mixes with the water so its not good. meee!
An experiment to show that ice melt faster in water that air?
get 2 icecubes that are similar sizes and put one in room temperature water and the other exposed to air.
How do you show that water vapor is surrounding the air using foil and ice?
If you wanted to demonstrate the presence of water vapor in the air, wrapping an ice cube in foil would allow water to condense out of the air and onto the foil, due to the lower temperature of the foil compared to the air.
