The root mean square speed -u- of hydrogen molecule is related to its pressure -P- and density -d- by the following expression-u-x221A-3Pd3180m-s-x221A-3P8-99-xD7-10-x2212-2kg-m3

The root mean square speed of hydrogen molecule of an ideal hydrogen gas kept in a gas chamber at 0∘C is 3180 metre/ second. The pressure on the hydrogen gas is: (density of hydrogen gas is 8.99×10−2kg/m3,1 atm=1.01×105N/m2).1.0 atmosphere1.5 atmosphere2.0 atmosphere3.0 atmosphere

The root mean square speed (u) of hydrogen molecule is related to its pressure (P) and density (d) by the following expression.u=√3Pd3180m/s=√3P8.99×10−2kg/m3

The root mean square speed (u) of hydrogen molecule is related to its pressure (P) and density (d) by the following expression.
$u = \sqrt{\frac{3 P}{d}}$
$3180 m / s = \sqrt{\frac{3 P}{8.99 \times 10^{- 2} k g / m^{3}}}$
