1
Systems left alone tend to move toward a state of
no entropy
less entropy
more entropy
2
The lowest possible temperature in nature is closest to
4 K
0 degrees C
-273 degrees C
3
80 J of thermal energy is added which then performs 55 J of work. Internal energy change is
25 J
135 J
55 J
0 J
4
5.1 g AU (.129) heated to 181 C then added to 10 ml H
2
O (4.186). If H
2
O incr. by 2 C, final T =
48.7 C
53.7 C
impossible to tell
127.3 C
5
Running a refrigerator with its door open in a hot room makes the room
larger
smaller
cooler
warmer
6
Cool air from zero C to near zero K and the air will lose
neither volume or pressure
volume and pressure
volume only
pressure only
7
The first law of thermodynamics is a restatement of the
conservation of energy
principle of entropy
law of heat addition
none of the above
8
Upon contact, If a warmer object gets warmer and a cooler gets cooler, this is a violation of
first law
second law
neither
both
9
Bouncing balls will not likely reorder themselves into a CoolWhip container because
there are more arrangements of that more ordered system
CoolWhip does not taste good
there are no arrangements of that more ordered system
there are fewer arrangements of that more ordered system
10
As a system becomes more disordered, entropy
increases
remains the same
decreases
