estimate number of impacts number of imapcts air molecule make with palm of your hand assuming all air is nitrogen molar mass =.0028

Answer 1

pressure*areaofHand=force=Numberhits*mass*velocity change

numberhits=air pressure*areaofhand/massN2*velocitychagne

but the change of velocity=2*Velocity (assumeing rebounds).
and velocity=function of temperature

so is this enough for you ? watch your units here.

Answer 2

How to get velocity=functionof temperature
