Boiling is the method of cooking food in boiling water or other water-based liquids such as stock or milk. [13] Simmering is gentle boiling, while in poaching the cooking liquid moves but scarcely bubbles. [14] The boiling point of water is typically considered to be 100 °C (212 °F; 373 K), especially at sea level.
DNB is also known as transition boiling, unstable film boiling, and partial film boiling. For water boiling as shown on the graph, transition boiling occurs when the temperature difference between the surface and the boiling water is approximately 30 to 130 °C (54 to 234 °F) above the T S. This corresponds to the high peak and the low peak on ...

An 'efficiency' value for a kettle can be defined as the ratio of the energy required to heat a desired volume of water (e.g. 220 ml standard cup) to the energy required to boil the kettle. For the plastic kettle, the minimum volume mark corresponded to 350 ml. Add to this the additional volume for the heat capacity (105 ml) and the efficiency ...

The high pressure limits boiling and creates higher temperatures not possible at lower pressures, allowing food to be cooked faster than at normal pressure. The prototype of the modern pressure cooker was the steam digester invented in the seventeenth century by the physicist Denis Papin. It works by expelling air from the vessel and trapping ...
