Question

Which temperature and pressure are used as standards for gases?

0°C, 1 atm


5°C, 2 atm


25°C, 1 atm


10°C, 1 atm

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

0°C and 1 atm

Step-by-step 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
