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

output?

explanation:

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
