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, ΔV/V0 = 6 ✕ 10-3) relative to the space available. Calculate the force exerted by the moonshine per square centimeter if the bulk modulus is 1.8 ✕ 109 N/m2, assuming the jar does not break.
 N/m2.In view of your answer, do you think the jar survives? (Hint: How many atmospheres is this?)

The bulk modulus is (ΔV/V)*ΔP

 

1.8*109 = 6*10-3*ΔP

ΔP= 3*1011 N/m2

 

105 N/m2 = 1bar (≈ 1atm) so ΔP ≈ 3*106 atm
