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

Answer : The correct option is, [tex]0^oC[/tex], 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, [tex]0^oC[/tex] or [tex]32^oF[/tex]

The pressure of gas is, [tex]1atm[/tex] or [tex]101.325kPa[/tex]

The volume of gas is, 22.4 L

Hence, the temperature and pressure used as standards for gases are, [tex]0^oC[/tex], 1 atm
