Kinetic Theory
The mass of a hydrogen molecule is 3.32 x 10-27 kg. If 1023 hydrogen molecules strike, per second, a fixed wall of area 2cm2 at an angle of 45° to the normal, and rebound elastically with a speed of 103 m/s, then the pressure on the wall is nearly:
4.70 x 102 N/m2
2.35 x 103 N /m2
4.70 x 103 N/m2
2.35 x 102 N /m2
B.
2.35 x 103 N /m2
