# Density Problems

1. The density of an uncooked egg is much less than that of a hard boiled egg. Would it make any difference in this demonstration if the egg was hard boiled? If yes, explain what you would see if the graduated cylinder contained:
a) only water
b) only salt water
c) 1/2 water, 1/2 salt water

2. Would a comparison of a can (12oz) of soda with a 16oz. bottle of beer, both of different masses be valid when considering their respective densities? Explain why or why not.

c) 1/2 water, 1/2 salt water

Response: Since the density of an uncooked egg is less than the density of a hardboiled egg, they will sink/float differently in water. In addition, we need to know that the density of salt water is greater than the density of plain water.

Therefore, if we put an uncooked egg in plain water, the egg will sink. In other words, the density of the egg is greater than ...
