Answer :
Answer:
a) We see that the change in volume is less for a lower pressure
b) The change in volume would be double
c) The change in volume of lead is four times that of gol
Explanation:
The change in volume with the pressure given by the Balk module
B = - P / (ΔV / V)
The minus sign is included so that the balk module is positive
a) let's clear the volume change
ΔV = - P V / B
When repression decreases the pressure change is negative
ΔV₂ = - P₀ V / B
We see that the change in volume is less for a lower pressure, so if the body is submerged when taking out the volume it increases
b) P₁ = ρ g h
ΔV₁ = - P₁ V / B
ΔV₁ = - ρ g h
P₂ = ρ g 2h
ΔV₂ = - P₂ V / B
Δv₂ = -ρ g 2h V / B
ΔV₂ = 2 DV₁
The change in volume would be double
c) Calculate the volume change for material
[tex]B_{Pb}[/tex] = ¼ [tex]B_{Au}[/tex]
ΔV = -p V / [tex]B_{Pb}[/tex]
ΔV = P V 4 / [tex]B_{Au}[/tex]
ΔV = 4 (-P V / [tex]B_{Au}[/tex] )
The change in volume of lead is four times that of gold
