Bernoulli equation | 5C18 | ||
blackbody | An idealized surface that is a perfect emitter and a perfect absorber. The absorptivity and the emissivity are both equal to 1 regardless of wavelength and angle of incidence. | 4B21 - 22 | |
blackbody | radiation | Radiation that is emitted from a blackbody. No surface can emit more energy than a blackbody. | |
boiler | 6B5 | ||
boiling | The process in which molecules move from the liquid phase to the vapor phase while the vapor pressure of the liquid is greater than the total pressure in the system. | 2A4 | |
boiling point | (also called steam point for water) At a given, fixed pressure, the boiling point is the temperature at which the first vapor bubble forms. At the boiling point, liquid and vapor are in equilibrium. On a PT Diagram, the vapor-liquid equilibrium curve is made up of the boiling points of the substance at different pressures. [ K, C, R, F ] | 2B2 | |
boiling point | normal | The boiling point of a substance at a pressure of one atmosphere. [ K, C, R, F ] | 2D9 |
boundary | A real or imaginary surface that separates the system of interest from its surroundings. | 1C2 | |
boundary work | Work done on or by a system that results in a change in the volume of the system. As a result of this volume change, the boundary of the system moves. That is why Boundary Work is sometimes called Moving Boundary Work. | 4A9 - 15 | |
boundary work | ideal gas | 4A18 , 19 | |
