What is the difference between STP and NTP?
and What is the volume of 1 mole of gas at STP and NTP?
Hi,
STP is Standard Temperature and Pressure. It is defined by IUPAC.
NTP is Normal Temperature and Pressure. These are the normal room temperature conditions.
STP is 0 ° C (273.15K) and 105 Pascal which is equal to 1 bar.
NTP is 20oC (293.15 K) and 1 atm which is equal to 101325 Pascal
By applying the ideal equation of state i.e. PV= nRT, we have
Volume of 1 mole of gas at STP is 22.7 L
Volume of 1 mole of gas at NTP is 24.0L
Hope this helps.
Cheers!
