Aclosed system consists of 0.4 kmol of propane occupying a volume of 10 m3 . determine
(a) the weight of the system, in n, and
(b) the mass-based specific volume, in m3 /kmol and m3 /kg respectively. let g = 9.81 m/s2 .

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
