Webbför 2 dagar sedan · In science, boiling happens when liquid becomes gas, forming bubbles inside the liquid volume. In cooking, water is the most frequently used liquid that is boiled. The temperature when water will begin to boil is around 212 degrees Fahrenheit/100 degrees Celsius. This is called the boiling point. WebbThat means that it won’t just evaporate from the surface but will form vapor bubbles, which then grow, inside the liquid itself. If the water has very few dust flecks etc. in it, this boiling process doesn’t happen until the temperature is significantly above 212°F, so you can temporarily have liquid water (called ’superheated’) above that boiling point.

Webb20 nov. 2024 · I'm confused about why the boiling of liquids happen. The boiling point of a liquid is defined as the temperature in which it's vapor pressure is equal to the pressure of the gas above the liquid( for example the atmospheric pressure ), and vapor pressure is defined as the (temperature dependent) partial pressure of the gas state of the liquid in … WebbWhen a liquid is heated, it eventually reaches a temperature at which the vapor pressure is large enough that bubbles form inside the body of the liquid.
