QUESTION:
Problem 44P
(II) How much pressure is needed to compress the volume of an iron block by 0.10%? Express your answer in N/m2, and compare it to atmospheric pressure (1.0 x 105 N/m2).
ANSWER:
Step-by-step solution
Step 1 of 3
V0=V (The initial volume of the iron block)
ΔV= - 0.1%= 0.001V (decrease in volume of the iron block under pressure change)
B=90x109N/m2 (bulk modulus of iron)
ΔP=? (the increase in pressure to change the volume of the iron block)
We are going to find the pressure which make the volume of the iron decrease by 10%.
