A student is planning an experiment to show how thermal energy can increase the molecular motion of gasses. Choose the experiment that would BEST show this relationship. What evidence would result from this experiment? * A. Experiment: A rubber balloon is secured to the top of a flask. The flask is placed in a cold ice bath. The balloon is observed over the next ten minutes. Evidence: The balloon would expand as the air in the flask expands.

B. Experiment: A rubber balloon is secured to the top of a flask. The flask is placed on a hot plate and heated on low. The balloon is observed over the next ten minutes. Evidence: The balloon would expand as the air in the flask expands.

C. Experiment: A flask is placed into a cold ice bath. After the flask has cooled to 32°F, a balloon is secured to the top of the flask. The balloon is observed over the next ten minutes. Evidence: The balloon would be sucked into the flask as the air in the flask contracts.

D. Experiment: A flask is placed in a warm water bath that is kept at a constant temperature of 150°F. After the flask has warmed to 150°F, a balloon is secured to the top of the flask. The balloon is observed over the next ten minutes. Evidence: The balloon would expand as the air in the flask expands.
