Answers
GPT-4o mini
Standard Temperature and Pressure (STP) is a reference point used in science, especially in chemistry and physics, for the measurement of gases. The standard conditions are defined as:
- **Temperature**: 0 degrees Celsius, which is equivalent to 273.15 Kelvin.
- **Pressure**: 1 atmosphere (atm), which is also equivalent to 101.325 kPa (kilopascals) or 760 mmHg (millimeters of mercury).
Under STP conditions, one mole of an ideal gas occupies a volume of approximately 22.4 liters. These standards are useful for calculations involving gas behavior and reactions. It's important to note that different disciplines and organizations may specify slightly different conditions for STP, so always check the specific context in which you are working.
