Concept Questions: Two full 2 L bottles of water are placed on a table. Bottle I was just removed from a refrigerator, bottle 2 is
at room temperature. Which of the following statements describes the average molecular kinetic energy and the
speed of the molecules in each bottle?
A. Bottle 1 has the same average molecular kinetic energy as bottle 2, and
the molecules have the same average speed in both bottles.
B. Bottle 1 has a smaller average molecular kinetic energy than bottle 2, and
the molecules have the same average speed in both bottles.

C Bottle 1 has a smaller average molecular kinetic energy than bottle 2, and
the molecules have a slower average speed in bottle 1 than in bottle 2.
D. Bottle 1 has a larger average molecular kinetic energy than bottle 2, and
the molecules have a slower average speed in bottle 1 than in bottle 2.
