Question

Numerical value of standard temperature is _________.

Answer 1

Hint: The standard temperature value is the standard value used for calculations in chemistry. It is used as a reference for calculating the values. It is a fixed value that is in kelvin. The standard temperature is used along with standard pressure and is called STP. It is used for mostly gaseous substances.

Complete answer:
The standard temperature is a condition for experimental measurements to be established to allow the comparisons to be made between different sets of data. The numerical value of the standard temperature is \[273.15\; K\]. The value of standard temperature is given by the International Union of Pure and Applied Chemistry (IUPAC) and the National Institute of Standards and Technology (NIST).
In chemistry, IUPAC changed the definition of standard temperature as the temperature of \[273.15\; K\] at $0$degree Celsius and $32$ degree Fahrenheit.
The standard temperature is usually used in a set along with standard pressure and together they are written as STP. The standard pressure value is $1$ atmosphere. These values of STP are often used to calculate the density and the volume of gases.
These values of STP are not universally accepted standards. Other organizations have established a variety of alternative definitions for their standard reference conditions. Under these conditions, scientists discovered that 1 mole of a gas, regardless of its identity, occupied a volume of 22.4 liters.

Note:
IUPAC has also given NTP which is normal temperature and pressure. The NTP value of temperature and pressure is \[293.15{\text{ }}K\] and \[1{\text{ }}atm\]. NTP is commonly used as a standard condition for testing and documentation of fan capacities.
