Liquids boil when the temperature of the liquid causes the liquid to turn from liquid to gas. With water this happens at about 100 degrees Celsius, or 212 degrees Fahrenheit.
The boiling temperature is dependent on the air pressure. If the pressure of the air is high, then it will press down on the liquid and prevent it from forming bubbles, but if the air pressure is less then the liquid will boil more easily. That's why water boils at a lower temperature when you are at the top of a mountain than when you are at sea level. The lower air pressure in the mts allows the water to turn into vapor more easily.

Depends on the substance and the air pressure. Water boils at 100C at 1 ATM
