Question

what are the values of STP

Answer 1

The values of STP is:
It’s defined as standard temperature and temperature, of 273.k(0 c 32 f and an absolute pressure of exactly 1 atom(101.325kpa).

Answer 2

Until 1982, STP was defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 1 atm (101.325 kPa). Since 1982, STP is defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 105 Pa (100 kPa, 1 bar).
