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.

Suppose you require 2500 food Calories per day. a. What is your average power, in watts? b. How much energy, in joules, do you require from food in a year? Counting all forms of energy (such as gasoline, electricity, and energy for heating), the average person consumes about 350 billion joules of energy each year. Compare this value to the energy needed from food alone. a. What is your average power, in watts? Approximately 121 watts (Round to the nearest whole number as needed.) b. The energy required from food is approximately billion joules per year. (Round to the nearest tenth as needed.)
