Standard Temperature and Pressure (STP) refer to a set of conditions commonly used as a reference point in various scientific calculations and experiments, particularly in chemistry and physics. The standard values defined for STP are:
- Temperature: 0 degrees Celsius (273.15 Kelvin)
- Pressure: 1 atmosphere (101.325 kPa or 760 mmHg)
These conditions provide a consistent baseline for comparing gas volumes and behaviors, following the ideal gas law and other related equations. Note that in some contexts, especially in different scientific communities, STP might be defined to involve slightly different parameters, but the values provided above are the most commonly accepted definitions.
