* Boiling point is dependent on pressure: The lower the pressure, the lower the boiling point. That's why water boils at a lower temperature on a mountaintop than at sea level.
* Different liquids have different boiling points: Water boils at 100°C (212°F) at standard atmospheric pressure, but ethanol boils at 78.37°C (173°F).
To determine the boiling point of a specific liquid, you need to know the pressure at which it's being heated.
Here are some additional points:
* Evaporation: Liquids can turn into gas below their boiling point through a process called evaporation. This happens because some molecules have enough energy to escape the liquid surface.
* Vapor pressure: Even at temperatures below the boiling point, liquids have a vapor pressure, which is the pressure exerted by the gas molecules above the liquid surface.
