Question

What is STP? Give the values of temperature and pressure at STP?

Answer 1

• Temperature and pressure have a great influence on the volumes of the gases.
• It is necessary to choose a suitable value for each as the standards.
• The conditions for standard temperature and pressure are given below:

Standard temperature = 0⁰C =273 K (Where C Celsius and K Kelvin scales).

Standard pressure = 760 mm of Hg(Mercury)= 1atm (1 atmospheric pressure).

• STP means Standard Temperature and Pressure.
• 0⁰C and 1 atm are the values of temperature and pressure which are considered Standard values.
