Question
The average speed of an oxygen molecule, in a container
of oxygen gas at room temperature, is 480 m/s. The
mass of an oxygen molecule is 5.31 x 10
The average speed of an oxygen molecule, in a container of oxygen gas at room temperature, is 480 m/s. The mass of an oxygen molecule is 5.31 Times 10-26 kg. Suppose an oxygen molecule is travelling at this average speed in the x-y plane, and strikes one wall of the container at an angle of 65o , as shown in the diagram. The molecule rebounds elastically with the same speed and angle. Calculate the impulse (magnitude and direction) delivered to the wall by the molecule. As this molecule bounces around inside the container, it strikes this same wall 780 Times each second. Calculate the average force that this one molecule exerts on the wall. What total force would one mole (6.02 x 1023) of these molecules exert on the wall?Explanation / Answer
a)
impulse is change in momentum (in horizontal direction) = 2* 5.31 x 10
