Question

in both STP and ntp pressure same or not​

Answer 1

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 (0° Celsius or 32° Fahrenheit) and the standard pressure is 1 atm pressure.

NTP - Normal Temperature and Pressure

NTP is commonly used  as a standard condition  for testing and documentation of fan capacities:

NTP - Normal Temperature and Pressure - is defined as air at 20oC (293.15 K, 68oF) 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)

At these conditions, the volume of 1 mol of a gas is 24.0548 liters.

STP stands for Standard Temperature and Pressure. NTP stands for Normal Temperature and Pressure. STP is set by the IUPAC as 0°C and 100 kPa or 1 bar. ... NTP is set at 101.325 kPa but uses 20°C as the temperature.
