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

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, , 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, or

The pressure of gas is, or

The volume of gas is, 22.4 L

Hence, the temperature and pressure used as standards for gases are, , 1 atm

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it
