Real gas and Ideal gas

Ideal gas : Any gas that obeys the ideal gas equation at all conditions of temperature and pressure is called ideal gas equation. Real gas : Any gas that obeys the Ideal gas equation only at low pressure and high temperature is called as Real gas.

What is STP In Chemistry?

Internationally STP is accepted as standard temperature and pressure. Mostly STP is used in the calculation of the density of gases molecule. In STP the temperature is 273K, pressure is 1 atm. Since temperature and pressure vary from place to place. T= 273K & P= 1atm
