Question

for thermodynamic, standard is 25 celsius and 10^5 Pa, so in this case does it mean that 1atm=10^5 Pa while for stp 1atm=101325 Pa

Answer 1

You can read about some of the history here. It's a little confusing because none of the so-called standards are accepted and used by everyone. And bar is thrown around inconsistently, also.
