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