what is the difference between STP and NTP |
|
Answer» Harsh mishra u are from DAV? Hi pratik STP is Standard Temperature and Pressure, where temperature is taken as 273K(0 C) and pressure is taken as 1 atm(1 atmosphere).Whereas NTP is Normal Temperature and Pressure, where temperature is taken as the normal room temperature(about 28-30 C) and pressure is taken as 1 atm. Wow what a great answer these r the toppers HARSH MISHRA STP\xa0stands for Standard Temperature and Pressure.NTP\xa0stands for Normal Temperature and Pressure.STP\xa0is set by the IUPAC as 0°C and 100 kPa or 1 bar.Many old books and online sources say that standard pressure is 101.325 kPa (the old IUPAC standard that was changed in 1982), but It defer to the current IUPAC standard of 100 kPa.NTP\xa0is set at 101.325 kPa but uses 20°C as the temperature.Note:0°C = 273.15K20°C = 293.15KAt STP:\xa0Pressure = 1 bar = 0.987 atm Temperature = 273 K or 0°CAt NTP:\xa0Pressure = 1 atm Temperature = 293 K or 20°CAlso,1 atm = 1.013 bar1 atm = 76.0 cm1 atm = 0.760 mHere,cm = centimetrem = metreatm = atmosphere |
