Question

In the field of chemistry, standard temperature and pressure conditions are:

Answer 1

Answer : The correct options are, 1 atm pressure and 273 K temperature.

Explanation :

STP : STP stands for standard temperature and pressure.

At STP,

The temperature is, $0^oC$ or $273K$ or $32^oF$

The pressure is, $1atm$ or $101.325kPa$  or $760mmHg$

The volume is, 22.4 L

Hence, the correct options are, 1 atm pressure and 273 K temperature.

Answer 2

Standard Temperature and Pressure (STP) conditions are:

1) 760 mmHg

2) 1 atm

3) 273.15 K (0 C, 32 F)

I'm not too sure if you mistyped your first bullet, but if you did not, it is not included as an STP condition - it must be millimeters.
