What is one bar of pressure ?

What is meant by one torr of pressure ?

A system consisting of 1 mole of an ideal gas undergoes an isothermal expansion at 25^(@) from 1.0 bar to a lower pressure while generating 100 J of work. What is the final pressure of the system if the external pressure of the system is constant of 0.1 bar?

A mixture of dihydrogen and dioxygen at one bar pressure contains 20% by weight of dihydrogen . What would be the partial pressure of dihydrogen in bar ?

If the mean free path is 10 cm at one bar pressure, then, its value in cm at 5 bar pressure, if temperature is kept constant will be :
