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.

What Is the Full Form Of UV

 What Is the Full Form Of UV The full form of UV is Ultraviolet and it a form of electromagnetic radiation. The word “Ultraviolet” also means beyond violet. The wavelength ranges from 10 - 400 nm. Since these waves are shorter than the visible light most humans cannot see the UV rays. Following are the abbreviations of UV subdivided into a number of ranges Name Abbreviation Wavelength (nm) Ultraviolet C UVC 100-280 Ultraviolet B UVB 280-315 Ultraviolet A UVA 315-400 Hydrogen Lyman Alpha H Lyman- α 121-122 Far Ultraviolet FUV 122-220 Middle Ultraviolet MUV 200-300 Near Ultraviolet NUV 300-400 Extreme Ultraviolet EUV 10-121 Vacuum Ultraviolet VUV 10-200   Who and When w

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
