4 pts Question 1 Your friend notices that a brown can of diet cola floats, while a green can of lemon-lime soda and a can of orange soda both sink. He postulates a model in which only nonbrown cans of soda sink. To test his model, he tries a brown can of diet root beer and finds that it floats. Your friend now tries a brown can of nondiet root beer and finds that it sinks. Which statement best describes the conclusion that can be made from this new observation? This observation does not constitute a useful test of the model; it neither supports nor refutes the model. This observation provides strong evidence to refute the model. O This observation provides some evidence against the model, but does not completely disprove it. This observation proves your friend's model This observation provides support for your friend's model but does not prove it.

Explanation / Answer

The correct answer is option (3) ==> The observation provides some evidence against the model, but does not completely disprove it.

Reasoning:

If we clearly observe the facts in this case, it is not just the color of the can, but the content and its composition of the can that really matters.

Let us consider that all the cans have exactly the same volume or size. But their density differs due to what is dissolved in the liquid content. By looking into the nutritional facts on a can of lime soda/orange soda/ non-diet root beer, we notice that it contains lot of sugar (sweetener) dissolved in it. This makes the density of the non-diet liquid greater than that of water. Therefore the non-diet Cola/soda/root beer sinks.

Diet sodas/diet root beer use artificial sweeteners. Normally the can of Diet beverage contains less than one gram of sweetener. Hence, diet beverage contains less sugar than non-diet beverage. Cans of diet soda/diet root beer are usually less dense than water. Therefore they float.
