Answer:

The average kinetic energy is increased by a factor of 3.

Step-by-step explanation:

The average kinetic energy is given by:


\overline{E} = (3)/(2)kT

Where:

k: is the Boltzmann constant

T: is the temperature

When the temperature is 300 K we have:


\overline{E_(1)} = (3)/(2)300k

Now, when the temperature is 900 K:


\overline{E_(2)} = (3)/(2)900k = 3((3)/(2)300k) = 3\overline{E_(1)}

Therefore, when the temperature is raised from 300 K to 900 Κ, the average kinetic energy is increased by a factor of 3.

I hope it helps you!
