NTP Full Form and STP Full Form in Chemistry

As the temperature and pressure vary at different places, a standard reference is needed for comparing the testing and the documentation of chemical processes and physical process. The NTP and STP respectively are used to define conditions. What is NTP full form and STP full in chemistry respectively is given below

NTP full form in chemistry

The NTP full form is Normal Temperature and Pressure defined by the National Institute of Standards and Technology (NIST). The NTP is widely used as a practical standard by Industries through the world because NTP conditions are more realistic and convenient condition.

• In NTP the normal temperature is 20-degree Celsius or 293.15 K or 68-degree F. This temperature is convenient to use as compared to 0-degree Celcius. 
• In NTP the normal pressure is 1 atm or 101.325 kpa or 760 mmHg (or torr) or 14.6959 psi
• One mole of an ideal gas occupies 24.0 litres (dm3)  of volume at NTP condition

STP full form in chemistry

The Full form of STP is Standard Temperature and Pressure defined by NIST. it is commonly used to state standard conditions for temperature and pressure.

• In STP the standard temperature is  0º C or 273 K) or 32 F
• The standard pressure is 1 atm or 760 mmHg
• 1 mole of an ideal gas occupies 22.4 litres (dm3) of volume at STP condition
