WHAT IS NTP AND STP?
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
Hope this helps.
Cheers!
