Question

What do you mean by NTP (normal temperature and pressure) and STP (standard temperature and pressure)?

Open in App

Solution

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 (20⁰C) and pressure is 1 atm pressure which is equal to 1.01325X 10⁵ Pascals.
