Question

Difference between STP AND NTP

Answer 1

Hey dud your answer is

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.

Many old books and online sources say that standard pressure is 101.325 kPa (the old IUPAC standard that was changed in 1982), but I defer to the current IUPAC standard of 100 kPa.

NTP is set at 101.325 kPa but uses 20°C as the temperature.

Answer 2

$\huge{Hey Mate!!!}$

☆☞ Here is ur answer ☜☆

✔✔ STP stands for standard temperature and pressure.

✔✔ These standards have been set by the IUPAC.

✔✔ For STP conditions, the temperature is 273.15K (00 C) and pressure is 1 bar (105 Pascals).

✔✔ NTP is defined as normal temperature and pressure. 

✔✔ For NTP conditions, the temperature is 293.15 K (200 C) and pressure is 1 atm pressure which is equal to 1.01325X 105 Pascals.
