Can compressed air put out a fire?

Why does canned air freeze upside down?
Because these gases are compressed to liquid form, when you turn the can upside down and press the nozzle, liquid will come out before it turns to gas. A pocket of gas sits at the top of the can, preventing liquid from spraying out when the can is right side up.
What happens when you spray canned air upside down?

Is compressed air more flammable?
Compressed air is not flammable. But feeding a burner of hydrocarbon-based fuels with compressed air increases the combustion rate, thus achieving a higher temperature of the flame.
Is it possible to start a fire with water?
