It is the temperature at which enough heat energy has been put into the molecules, overpowering the hydrogen bonding between molecules. Water at the atmospheric pressure of sea level boils at 100 degrees Celsius (or 212 degrees Fahrenheit or 373.15 degrees Kelvin).

Water boils at a specific temperature (100°C or 212°F at sea level) because that is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. At this point, the liquid can overcome the pressure and transition into a gas state. This temperature is a physical property of water and remains consistent under standard conditions.
Adding salt to boiling water will actually make the water boil slower. Salt increases the boiling point of water by raising its boiling point temperature. As a result, it will take longer for the water to reach the new, higher boiling point temperature and thus boil.
No, rainwater and seawater will not boil at the same temperature. Seawater has a higher boiling point than rainwater due to the presence of dissolved salts and minerals, which raise the boiling point of the water.
Vacuum boiling is a process of bringing water to a boil using reduced air pressure. This lowers the boiling point of water, allowing it to boil at lower temperatures. It is often used in industrial settings or labs where precise temperature control is needed.
Yes. Dissolved substances increased the boiling point.
Technically speaking, boiling is when the pressure inside the system is equal to that of the surroundings. That means that you can boil water at room temperature if you have a vacuum pump. If you mean just to the heat that it starts to boil at STP, then no, it doesn't. Boiling point at STP is and always will be 100 degrees Celsius.
