The liquid starts boiling
By reducing the pressure
The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
Absolutely. The most obvious examples are vaporization of a liquid when the pressure is lowered. For example, if you release the fuel in a disposable lighter, the liquid butane becomes a gas when it reaches the lower pressure of the atmosphere. You can demonstrate this with water by putting it in a syringe, closing the end, and rapidly pulling out the plunger. The water will actually bubble and boil at room temperature.
Yes it is possible. Boiling takes place when the saturated vapour pressure becomes equal to the surrounding pressure. So by reducing pressure over the surface of liquid even at 20 deg celsius it is possible to boil.

The liquid starts boiling
Boiling and melting points depend on both temperature and pressure. While the common way to boil something is to heat it, lowering the pressure significantly will also make it boil. For example, in the vacuum of space water will boil even when below zero degrees Celsius, but can be kept liquid well above 100 degrees Celsius if put under significant pressure.
Liquids can boil at low pressure, and in fact do so at lower temperatures than when the pressure is high.
The nature of the liquid and the pressure.
It will boil
Any addition of thermal energy to a saturated liquid will cause it to vaporize. Any subtraction of thermal energy from a saturated vapor will cause it to condense.
the point at which a liquid starts to 2 boil is defined by when the pressure inside the liquid is equal to the atmospheric pressure. so the higher the altitude the lower the pressure, which means the temperature at which the liquid will start 2 boil will b lower. this applies for when a gas goes to a liquid as well
