Question

At room temperature, an oxygen molecule, with a mass of 5.32 X 10^-26 kg, typically has a kinetic energy of about 6.21 X 10^-21 J. How fast is the molecule moving?

Answer 1

v = 483.1 ms⁻¹

Step-by-step explanation:

Kinetic energy is the energy possessed by a moving object solely due to its motion.

You can get the K.E. of an object using the equation,

K.E. = (1/2)mv²

So you get, for molecule,

K.E. = 6.21 X 10^-21 = (1/2)×5.32 X 10^-26×v²

we get, v = 48.31 ms⁻¹
