Question

A child has a bucket full of toys: foam alphabet letters, action figures, and toy cars.

Dumping the toys into the child's bathwater to separate the foam alphabet letters from the mixture is taking advantage of which physical property?
A. size
B. density
C. magnetism
D. boiling point

Answer 1

the answer is density because the foam letters are denser meaning they will float to the surface quicker than the other toys

Answer 2

Answer: B. Density

Explanation:

Density is the comparison between the amount of matter contained by an object and its volume.

Mathematically, density is defined as; d = m/v

Where d is density

m is mass

and v is volume.

Dumping the toys in the bathwater is taking advantage of density because foam is generally less dense than water and anything less dense than water will float in water.

So, there will be a separation based on density because the foam alphabet letters will float while the other toys will sink due to the fact that they are denser and heavier than water and their molecules are compact; very close together.
