👉 The standard fluid, commonly referred to as "standard atmospheric pressure" or "STP," is a term used in chemistry to describe a specific set of conditions under which gases behave predictably. At STP, which is defined as 0 degrees Celsius (273.15 Kelvin) and 1 atmosphere of pressure, the behavior of gases is governed by well-defined constants. Specifically, at STP, one mole of any ideal gas occupies 22.414 liters, regardless of the gas's chemical composition. This standardization allows chemists to compare and predict the behavior of different gases under similar conditions, facilitating accurate calculations and experiments.
