Concept question 1
The San Gorgonio Pass wind farm, near Palm Springs, is one of
three major wind farms in California. Determine which of the
following are properties and which are not properties of the
wind farm (or some subsystem thereof):
(a) Number of wind turbines on the wind farm
(b) Mass of birds killed by colliding with turbine blades in
the year 2019
(c) Latitude & longitude of the wind fam
(d) Total number of rotations of all turbines on March 17,

(e) Circumference of the circle swept out by an individual
blade over the course of 1 revolution
(f) Temperature of turbine blade
(g) Electrical power produced by the wind farm over the course of a month
(h) Date of manufacture of a turbine
(i) Color of turbine blade
Concept question 2
As a demonstration of the conversion of potential
into internal energy, you drop a 1-kg ball of Silly
Putty off a tall building from a height of h= 100 m.
Initially, the putty is at 300 K, and the surrounding
air is also at 300 K. Determine the rise in
temperature of the putty right after it impacts the
ground (before starting a heat transfer interaction
with the environment). Assume the putty to be an
incompressible solid with specific heat
c = 2500 J/kg-K. Assume the gravitational
acceleration is g = 9.81 m/s².
