Homework Statement



1) 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 1.9 ✕ 109 N/m2, assuming the jar does not break.
Answer --- N/cm2

I basically re read the textbook for that and got no where. I have no equations and don't know where to start.

such problems should be posted one per thread, otherwise things can get confusing.

Ok, is that better? Do you have any help for me?

Not yet. You deleted part of the template and you did not show your attempt at solution.

We are not allowed to just give you the answer. We help with hints or showing where you went wrong, but you have to do the work. So please post your attempt at solution, and the next time fill out the whole template.

What textbook are you using? Every intro physics book I've seen introduces an equation with a constant and then tells you the constant is called the bulk modulus. Does your book really just throw that constant out there without telling you what it represents?

Here's a place to start: What is the meaning of the bulk modulus? Have this question in mind when you read the textbook again. Reading tends to be more effective when you're looking for specific information. Come back and tell us in your own words your understanding of what the bulk modulus represents.
