Concept explainers
(a)
Interpretation:
Value of factor change in pressure and root mean square speed if gas is compressed into third of its original volume has to be determined.
Concept Introduction:
Root mean square speed is square root of average value of square of molecular speeds of molecules of gas. It includes molecular weight and temperature, both of which affect kinetic energy of a gas. It is denoted by
