What is the likely reason that Boat B is sitting lower in the water? 

• Boat B is smaller than Boat A, which makes it sink. 
• Boat B has less mass than Boat A, which makes it sink.
• Boat B has more mass than Boat A, which makes it sink.
• Boat A cannot float, which makes it sink.

How are solutions different from mixtures? 

• solutions are easily separated, while mixtures are NOT easily separated
• solutions form new substances while mixtures do not form new substan
