When we place a gas cylinder on a van and the van moves, does the kinetic energy of the molecules increase?Does the temperature increase?

The kinetic energy of molecules of gas (temperature) will increase only when there is a changein velocity( it starts , it stops , there is a change in speed , direction).

What is meant by the term ' Molar specific heat ' of a gas?  The molar specific heat of hydrogen in the temperature range of about 250 K to 750 K is about (5/2) R.  At lower temperatures the value of molar specific heat of hydrogen decreases to the value typical of monoatomic gases (3/2) R while at higher temperatures, it tends to the value (7/2) R.  Explain.
