Boiling and evaporation are the two main forms of liquid vaporization. There are two main types of boiling: nucleate boiling where small bubbles of vapour 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 … See more Boiling is the rapid phase transition from liquid to gas or vapor; the reverse of boiling is condensation. Boiling occurs when a liquid is heated to its boiling point, when the temperature at which the vapour pressure of … See more Pool boiling "Pool boiling" refers to boiling where there is no forced convective flow. Instead, the flow occurs due to density gradients. It can experience any of … See more Refrigeration and air conditioning Most types of refrigeration and some type of air-conditioning work by compressing a gas so that it … See more • Phase diagram • Phase transition • Explosive boiling or phase explosion • Recovery time (culinary) • Enthalpy of vaporization See more Free convection The lowest heat flux seen in boiling is only sufficient to cause [natural convection], where the warmer fluid rises due to its slightly higher … See more The boiling point of an element at a given pressure is a characteristic attribute of the element.
