In lab we determined the specific heat of several cubes of metal. One of those cubes was lead which had a specific heat of 0.13 J/g oC. Let’s imagine a thought experiment where we drop a 100 g piece of lead off the roof of a 10 meter tall building. A. How much will the temperature rise for the lead when it hits the ground? B. How much potential energy does the lead have at the top of the roof? C. How much kinetic energy does the lead have just prior to striking the ground? Assume that the mechanical energy is conserved and transferred to the lead to be thought of as heat, Q. Using Q = mc(T-To), solve for (T-To), the change in temperature.

Question
In lab we determined the specific heat of several cubes of metal. One of those cubes was lead which had a specific heat of 0.13 J/g oC. Let’s imagine a thought experiment where we drop a 100 g piece of lead off the roof of a 10 meter tall building.
A. How much will the temperature rise for the lead when it hits the ground?
B. How much potential energy does the lead have at the top of the roof?
C. How much kinetic energy does the lead have just prior to striking the ground?
Assume that the mechanical energy is conserved and transferred to the lead to be thought of as heat, Q. Using Q = mc(T-To), solve for (T-To), the change in temperature.
