STP in physics and chemistry stands for standard temperature and pressure.
Generally the standard temperatures used for measurements in chemistry and physics are O 0C (IUPAC rules) or 20 0C (NIST rules).
Journal of Low Temperature Physics was created in 1969.
Normal temperature pressure refers to conditions at 0°C (273K) and 1 atm pressure, while standard temperature pressure refers to conditions at 25°C (298K) and 1 atm pressure. These conditions are used as reference points for certain calculations and measurements in chemistry and physics. The main difference is the temperature at which they are defined, with standard temperature pressure being at a slightly higher temperature than normal temperature pressure.
Measurement in physics is the process of quantifying physical quantities such as length, time, mass, and temperature using standard units. It is essential for gathering data, conducting experiments, and verifying theories in physics. Accurate and precise measurements are crucial for understanding and predicting the behavior of physical systems.
The standard temperature is 0 degree Celsius.
Physics has its own vocabulary. One measurement in physics is the Dyne. Physics also deals with vectors, tension and torque. Common to other sciences, physics uses the standard metric measures of grams, liters and meters.
The standard unit of pressure measurement in physics known as the bar is equal to 100,000 pascals.
The solubility depends on the temperature; and because 20 0C is considered a normal room temperature, this temperature is frequently used as a standard. The temperature of 25 0C is rarely used but it is your choice, depending on the application, to consider any temperature. The problem of standard conditions is not solved; different countries and organizations use similar but not identical temperatures and pressures as standards. The understanding between scientists involve a severe standardization in all fields to correct comparison of the results of experiments. An aside: 20o C is considered more a physics standard temperature while 25o C is The IUPAC standard and is used in most chemistry experimental as the standard temperature.
There is no internationally agreed standard temperature.

298 K is the standard room temperature, while 273.15 K is the standard temperature for converting Celsius to Kelvin.
