The Boiling Point: Why Water Bubbles at 100°C

Boiling Defined: Boiling happens when liquid molecules gain enough energy to turn into gas.
100°C Mark: At sea level, water boils at 100°C (212°F), its standard boiling point.
Bubble Birth: Bubbles form when vapor pressure inside them equals outside air pressure.
Heat Energy: Added heat breaks hydrogen bonds, freeing water molecules to escape.
Altitude Effect: Higher up, with lower air pressure, water boils at cooler temperatures.
Pressure Cooker Trick: Extra pressure raises the boiling point, cooking food faster.
Not Just Heat: Impurities like salt or sugar can change the boiling point slightly.
Rolling Boil: Vigorous bubbles mean the whole liquid has reached boiling temperature.
Cooling Role: Boiling removes heat through steam, a natural cooling process.
Everyday Wonder: From kettles to pasta pots, boiling is science happening in your kitchen.
