Hot lead with a mass of 200.0 g of (Specific heat of Pb = 0.129 Jig'C) at 176.4°C was dropped into
a calorimeter containing an unknown volume of
water. The temperature of the water increased
from 21.7°C to 56.4°C. What volume of water is
in the calorimeter?
a. 11. 32 mL
b. 21.32 mL
C. 12.23 mL
d. 31.21 mL

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
