Steel Boiling Point: Quiz and Flashcards

Study Notes

Boiling is the rapid phase transition from liquid to gas or vapor, and the reverse of boiling is condensation. The two main types of boiling are nucleate boiling, where small bubbles of vapor form at discrete points, and critical heat flux boiling, where the boiling surface is heated above a certain critical temperature and a film of vapor forms on the surface. The boiling point of water is 100 °C or 212 °F but is lower with the decreased atmospheric pressure found at higher altitudes. Boiling water is used as a method of making it potable by killing microbes and viruses that may be present. Boiling water is also used in several cooking methods including boiling, steaming, and poaching. The boiling point of an element at a given pressure is a characteristic attribute of the element. Mixtures of volatile liquids have a boiling point specific to that mixture producing vapor with a constant mix of components - the constant boiling mixture. Most types of refrigeration and some type of air-conditioning work by compressing a gas so that it becomes liquid and then allowing it to boil. Boiling is the method of cooking food in boiling water or other water-based liquids such as stock or milk. Simmering is gentle boiling, while in poaching, the cooking liquid moves but scarcely bubbles. At any given temperature, the molecules in a liquid have varying kinetic energies. Some high energy particles on the liquid surface may have enough energy to escape the intermolecular forces of attraction of the liquid and become a gas. This is called evaporation.
