Answer:
As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container
Explanation:
<span> For this case we have the following number:
1,000,000
We note that the number has 7 significant figures.
To write it in scientific notation we must write the number as follows:
</span>

<span> Where,
a: first significant figure
b: Exponent that represents the rest of significant figures.
Rewriting the number we have:
</span>
