Rolling boil of water in an electric kettle. Boiling or ebullition is the rapid phase transition from liquid to gas or vapour; the reverse of boiling is condensation.Boiling occurs when a liquid is heated to its boiling point, so that the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.
Bumping is a phenomenon in chemistry where homogeneous liquids boiled in a test tube or other container will superheat and, upon nucleation, rapid boiling will expel the liquid from the container. In extreme cases, the container may be broken.
[40] [41] [42] The small, black to brown earthenware vessel is a cookware-cum-serveware used for various jjigae (stew), gukbap (soup with rice), or other boiled dishes in Korean cuisine. As a ttukbaegi retains heat and does not cool off as soon as removed from the stove, stews and soups in ttukbaegi usually arrive at the table at a bubbling ...
Superheating can occur when an undisturbed container of water is heated in a microwave oven. At the time the container is removed, the lack of nucleation sites prevents boiling, leaving the surface calm. However, once the water is disturbed, some of it violently flashes to steam, potentially spraying boiling water out of the container. [6]
Stone boiling is a moist-heat cooking method. It involves placing heated rocks into a water-filled container to heat the liquid to the point where it can be used to ...
Boil-in-bags are a form of packaged food products in which bagged food is heated or cooked in boiling water. Plastic bags can be solid and impermeable for holding frozen foods; alternatively, bags can be porous or perforated to allow boiling water into the bag. Food packaged in this manner is often sold as boil-in-the-bag. [1]
A Florence flask/boiling flask is a type of flask used as an item of laboratory glassware and is named after the city Florence. [1] It is used as a container to hold liquids. A Florence flask has a round body, a long neck, and often a flat botto
