10. To compute the volume change of the solid copper cube, we can use the formula:
ΔV = -V * ΔP / B
where ΔV is the volume change, V is the initial volume of the cube, ΔP is the change in pressure, and B is the bulk modulus.
Given:
Initial volume (V) = 6.4 * 10^-5 m^3
Change in pressure (ΔP) = 20 * 10^6 Pa
Bulk modulus (B) = 125000 * 10^6 Pa
Substituting the values into the formula:
ΔV = -(6.4 * 10^-5) * (20 * 10^6) / (125000 * 10^6)
= -1.024 * 10^-3 m^3
Therefore, the volume change of the solid copper cube is -1.024 * 10^-3 m^3.
a. -1.024 * 10^-3 m^3
11. The total energy content of a system which is equal to the sum of all forms of energy possessed by the atoms and molecules of the system is known as internal energy.
c. internal energy
