Water boils at 100 °C...or does it? See how to get water to boil at room temperature, and how you can boil water at 40 °C using supplies you probably have around your house!
To make good tea, you need temperatures of 75-95 °C, depending on the variety. On Mt. Everest, water boils at a temperature of 68 °C! So without a pressure cooker, your tea is always going to suck.
In order to boil, water molecules need to gain enough kinetic energy to overcome the hydrogen bonds between gas molecules, but also get past the barrage of atmosphere molecules crashing into them. By reducing the amount of atmosphere above the water, the boiling point can be reduced! Hydrogen bonding explained!
