The reason it is hard to observe a liquid transforming to a perfectly solid âideal glassâ is that to do so we would have to wait an extraordinarily long time (much longer than centuries) because the process is very slow. But the behaviour of viscous liquids is more surprising than simply having to wait a long time.
Definition. Standard Temperature and Pressure (STP) is defined as 0 degrees Celsius and 1 atmosphere of pressure. Do not confuse STP with the STP Products Company, a maker of oil and fuel additives...unless you are reading one of their MSDS's! Additional Info. STP is used in many thermodynamic calculations and tabulations. Certain properties of matter such as density, viscosity, boiling point etc. will vary with changes in temperature or pressure. Having one common set of conditions (state) for tabulating these values makes comparisons possible and eases calculations.
Answer: STP in chemistry is the abbreviation for Standard Temperature and Pressure. STP most commonly is used when performing calculations on gases, such as gas density.The standard temperature is 273 K (0Â° Celsius) and the standard pressure is 1 atm pressure.At STP, one mole of gas occupies 22.4 L of volume (molar volume).STP commonly is used when standard state conditions are applied to calculations.Standard state conditions, which include standard temperature and pressure, may be recognized in calculations by the superscript circle.t STP, one mole of gas occupies 22.4 L of volume (molar volume). STP commonly is used when standard state conditions are applied to calculations.
