Vapor print that page

Watervapor_cup

A vapor (American spelling) or vapour (see spelling differences ) is a substance in the gas phase at a temperature lower than its critical point . [ 1 ] This means that the vapor can be condensed to a liquid or to a solid by increasing its pressure without reducing the temperature

Water vapor print that page

St_Johns_Fog

individual water molecule which transitions between a more associated (liquid) and a less associated vapor /gas) state does so through the absorption or release of kinetic energy. The aggregate measurement of this kinetic energy transfer is defined as thermal energy and occurs only when there

Vapor-compression refrigeration print that page

Screw_compressors

performs this function may also be called a heat pump . Contents 1 Description of the vapor -compression refrigeration system 1.1 Refrigerants 2 Thermodynamic analysis of the system 3 Types of gas compressors 3.1 Reciprocating compressors 3.2 Rotary screw compressors

Plasma-enhanced chemical vapor deposition print that page

STS_multiplex_PECVD_machine_at_LAAS_0495

A plasma is any gas in which a significant percentage of the atoms or molecules are ionized. Fractional ionization in plasmas used for deposition and related materials processing varies from about 10 −4 in typical capacitive discharges to as high as 5–10% in high density inductive plasmas

Vapor lock print that page

winter to improve the starting of the engine, the use of "winter" fuels during the summer can cause vapor lock to occur more readily. Contents 1 Causes and incidence 2 Motorsports 3 Incidence with other fuels 4 See also [ edit ] Causes and incidence Vapor lock was far

Vapor pressure print that page

Water_vapor_pressure_graph

The equilibrium vapor pressure is an indication of a liquid's evaporation rate. It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapor pressure at normal temperatures is often referred to as volatile . The vapor pressure of any substance

Chemical vapor deposition print that page

PICT0111

and ultra-high vacuum is common, often 10 −7 Pa. Classified by physical characteristics of vapor Aerosol assisted CVD (AACVD) – A CVD process in which the precursors are transported to the substrate by means of a liquid/gas aerosol, which can be generated ultrasonically. This technique

Raoult's law print that page

Graph-for-raoults-law

Established by François-Marie Raoult in 1882, [ 1 ] Raoult's law states: the vapor pressure of an ideal solution is dependent on the vapor pressure of each chemical component and the mole fraction of the component present in the solution . [ 2 ] Once the components in the solution

Hybrid Physical-Chemical Vapor Deposition print that page

HPCVD_chamber

at the same time. Above certain temperature, the bulk metal source melts and generates a high vapor pressure in the vicinity of the substrate . Then the precursor gas is introduced into the chamber and decomposes around the substrate at high temperature. The atoms from the decomposed precursor

Vapor quality print that page

In thermodynamics , vapor quality is a quantitative description of the usefulness of a vapor to do mechanical work . The quality of a fluid is the percentage of mass that is vapor ; [ 1 ] i.e. saturated vapor has a "quality" of 100%, and saturated liquid has a "quality" of 0%. For instance
