Question

A moonshiner makes the error of filling a glass jar to the brim and capping it tightly. The moonshine expands more than the glass when it warms up, in such a way that the volume increases by 0.6% (that is,

?V/V₀ = 6.
A moonshiner makes the error of filling a glass jar to the brim and capping it tightly. The moonshine expands more than the glass when it warms up, in such a way that the volume increases by 0.6% (that is, ?V/V0 = 6. Times 10-3) relative to the space available. Calculate the force exerted by the moonshine per square centimeter if the bulk modulus is 2.1 Times 109 N/m2, assuming the jar does not break. How many atmospheres is this?
10^-3) relative to the space available.

(a) Calculate the force exerted by the moonshine per square centimeter if the bulk modulus is

2.1 10⁹ N/m², assuming the jar does not break.

(b) How many atmospheres is this?

Answer 1

Answer 2

a) Force exerted by moonshine per square meter = Bulk modulus *?V/V₀

=2.1 10⁹x 6.0 10^-3

= 12.6 x 10^6 N/m^2

Force exerted per square centimeter = 12.6 x 10^6 x 10^-4 = 1260 N/cm^2

b) 1 atm =1 x 10^5 N/m^2.

So, force exerted here = 126 atm.

Answer 3

a) B=-V*dp/dv

or 2.1*10^9=P/(6*10^-3)

or P=1.26*10^7 N/m^2

=1.26*10^3 N/cm^2

b)pressure=124.75 atms
