Question

What is true at STP?

Answer 1

STP stands for standard temperature and pressure and it is at a temperature of 0 degrees Celsius or at 273 Kelvin and at a pressure of 101.325 kPa or 1 atm. For gases, at this temperature it was established that for every one mol of a gas it is equivalent to 22.414 Liters.

Answer 2

Answer:

1 mole of gas  approximately occupies  22.14 liters volume at STP

Explanation:

STP ( standard temperature and pressure ) this is a standard set conditions that are set for the purpose of comparing different set of data. like the temperature in solid substance with the temperature with other forms of  substance like gases and liquid. and also the pressure of different substances taking the standard pressure value which is an absolute pressure of 1 atm is used as a yardstick for calculations/comparison.

The standard temperature at STP is recorded as 273 k or 0 degree Celsius with an absolute/standard pressure of 1 atm.
