standard temperature and pressure formula
The standard temperature is the freezing point of water and the standard pressure is one standard atmosphere. These can be quantified as follows: Standard temperature: 0Â°C = 273.15 K Standard pressure = 1 atmosphere = 760 mmHg = 101.3 kPa Standard volume of 1 mole of an ideal gas at STP: 22.4 liters.Standard pressure = 1 atmosphere = 760 mmHg = 101.3 kPa. Standard volume of 1 mole of an ideal gas at STP: 22.4 liters.n such a gas, all the internal energy is in the form of kinetic energy and any change in internal energy is accompanied by a change in temperature. An ideal gas can be characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T).
