The first propellants were used for engines. Propellants help the aircraft move forward. Moving forward at high speeds causes lift around wings.

Why are volatile liquids often used in aerosol spray cans?
What kind of liquids are you talking about? ... and why do you mean volatile? Do you mean flammable? The question refers to the propellants used in aerosol spray cans. If aerosol cans were filled with compressed gas, they would have to be designed to withstand extremely high pressures, which would not be cost-effective. Instead, liquid propellants (usually butane, isobutane or propane) are used, which allow a much larger amount of propellant to be stored, at a reasonable pressure. These liquid propellants are "volatile" in the sense that a small amount of the liquid evaporates every time some of the gas is released, so that the vapor and liquid stay in equilibrium. As it happens, most of these liquid propellants are also flammable, but the term "volatile" refers to their tendency to evaporate.
Why volatile liquids are often used as propellants in aerosol spry cans of such things as paints and deodorants?
Because non-volatile liquids don't work.
