A boil occurs when large bubbles come from the bottom of the pot and quickly rise to the surface, producing constant steam. At sea level, the boiling point is 212°F; at high altitudes, liquids boil at lower temperatures due to a change in atmospheric pressure.

Why do things boil?

Boiling occurs when enough particles in a liquid escape en masse from the liquid to form bubbles of gas in the body of the liquid. These gas bubbles then rise to the surface of the liquid and the liquid is said to boil. The temperature at which a liquid boils is affected by atmospheric pressure.

Is Sweating an example of evaporation?

One important example of evaporation is sweating. The sweat requires energy to evaporate off of your skin. It gets that energy from the excess heat your body is producing, in turn causing you to cool down.

Evaporation is a process where liquids change to a gas or vapor. Water changes to a vapor or steam from the energy created when molecules bounce into one another because they’re heated up. Sweat drying from our body is a great example of evaporation.

What is a slow boil?

What does boil mean in cooking?

212 °F
boiling, the cooking of food by immersion in water that has been heated to near its boiling point (212 °F [100 °C] at sea level; at higher altitudes water boils at lower temperatures, the decrease in boiling temperature being approximately one degree Celsius for each 1,000 feet [300 metres]).
