Well, these particles happens to be small, like REALLY small. So microscopically small they aren't picked up or observed my the naked eye. also the vibrations are in an atomic scale which is also VERY tiny This goes for all solids too.
Answer:
<h2>12 atm</h2>
Explanation:
To find the initial pressure we use the formula for Boyle's law which is
Since we are finding the initial pressure
From the question we have
We have the final answer as
<h3>12 atm</h3>
Hope this helps you
Density= mass/ volume
So density = 99/10= 9.9g/cm^3
Hope this helps!! xx
