Difference Between STP and NTP

 Difference Between STP and NTP The STP and NTP are the conditions used in chemistry, biology and engineering field to specify the conditions. For example, physical properties like viscosity, freezing point change with respect to temperature and pressure. In general, these properties are specified at STP and NTP conditions. The the full forms and Difference between STP and NTP is given below STP STP stands for standard Temperature and pressure Temperature in STP is 273.15 K (0°C) Pressure is 0.987 atm (1 bar) Molar volume of gas at STP is 22.4 L NTP NTP stands for normal temperature and pressure Temperature is 293.15 K (20°C) Pressure is 1 atm Molar volume of gas at NTP is 2.24 L I hope this clears what is the difference between STP and NTP  in science.

NTP Full form in Chemistry, Medical and Engineering

NTP Full form in Chemistry You may haven often seen this abbreviationNTP in the field of chemistry, medical and engineering thermodynamics. The NTP full form is normal temperature pressure condition and is defined as air at 20 ° C (293 k ) and 1 atm (101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 29.92 in Hg, 407 in H2O, 760 torr). Density 1.204 kg/m3 (0.075 pounds per cubic foot) Under these conditions the volume of air or any gas (also called molar volume) at 1 mol is 24.0548 liters Example 1 Calculate the volume of 0.223 moles of nitrogen at NTP Solution: At NTP condition, 1 mol of nitrogen at P =1 atm and T= 293 K occupies 24.0548 liters So, Volume of 0.223 moles of Nitrogen = 24.0548 * 0.223 = 5.3642 liters     Example 2 Calculate the moles of 5.37 liters of nitrogen at NTP condition Solution: The molar volume of Nitrogen at NTP condition = 24.0548 liters So, Moles of Nitrogen at NTP = 5.37 / 24.0548 = 0.223 moles   Read more : Full form of STP
