Question

Standard temperature and pressure (STP), in the context of gases, refers to a) 298.15 K and 1 atm b) 273.15 K and 1 atm c) 298.15 K and 1 torr d) 273.15 K and 1 pascal e) 273.15 K and 1 torr is a valid statement of Charles' law.

Answer 1

Answer : The correct option is, (B) 273.15 K and 1 atm

Explanation :

STP : STP stands for standard temperature and pressure.

STP conditions :

The temperature is, $0^oC$ or $273.15K$ or $32^oF$

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

The volume is 22.4 L for 1 mole of a substance.

Hence, the correct option is, (B) 273.15 K and 1 atm
