Homework Statement Why can we assume that atoms in a solid material act like hard balls? The Attempt at a Solution because they are tightly packed together when in a solid state[/B]

Thank you so much :)

nothing

when i have the volume i will use it to find the pressure like so P = (n(8314)(281)) / V

i know i need to find the volume of the sphere for the first part but iam unsure of how to get a number for n

the first part first of all,but there are two unknown variables so I'm not sure what to do

does anyone know how to do this question. it feels like there's a part of the question missing as i don't know how to complete the equation The pressure of a fixed mass of gas in a sealed sphere is measured to be 1.02 x 10^5 Pa at a temperature of 253K. Assuming the volume of the sphere doesn't...
