Question

Which temperature and pressure are used as standards for gases?

Answer 1

Answer : The correct option is, $0^oC$, 1 atm

Explanation :

STP : STP stands for standard temperature and pressure of the gas.

As we know that at STP,

The temperature of gas is, $0^oC$ or $32^oF$

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

The volume of gas is, 22.4 L

Hence, the temperature and pressure used as standards for gases are, $0^oC$, 1 atm

Answer 2

Answer:

0°C and 1 atm

Explanation:

This are the conditions of temperature and pressure defined by IUPAC as standard.

But also, the definition used by the NIST considerates a temrperature of 20°C and a pressure of 1 atm
