Question

An unopened can of Coke or Pepsi will sink when put in water. An unopened can of Diet-Coke or Diet-Pepsi will float. Try the experiment to verify the assertion. Explain the phenomenon.a) diet-coke has less sugar, so it sinks and regular coke has more sugar, so it floats. b) diet-coke has more sugar, so it floats and regular coke has less sugar, so it sinks. c) diet-coke has less sugar, so it floats and regular coke has more sugar, so it sinks. d) diet-coke has less sugar, so it floats and regular coke has more sugar, so it floats.

Answer 1

The answer is 3. The addition of sugar increases the density of the coke, when the density is higher then the density of water the coke sinks, but less sugar as in a diet-coke make the densisty lower than the water density and therfore it floats.
