(I) At room temperature, an oxygen molecule, with mass of 5.31 X 10-26 kg typically has a kinetic energy of about 6.21 X 10-26 kg, How fast is it moving?
Step 1 of 1
Mass of the oxygen molecule:
Kinetic energy of the molecule is:
The speed of the molecule is:
It is useful to notice that the sign v comes from the word velocity, which is different from the speed in a sense that velocity is a vector, and speed is absolute value of velocity and its a scalar. In our case we were asked for the speed but in this case we use the same sign for both speed and velocity.
If we know kinetic energy and either mass or the speed, we can easily calculate the other unknown value.
