Question

Your lab partner takes a knife and cuts his ball of PlayDough into two pieces. How did the density of his PlayDough change?

A) The density increased.
B) The density decreased.
C) The density remained the same.
D) It depends on the size of the two pieces.

Answer 1

The density of the PlayDough remains unchanged after cutting it into two pieces because density is an intensive property that does not depend on the material's size.

Step-by-step explanation:

When your lab partner cuts a ball of PlayDough into two pieces, the density of the PlayDough remains the same. Density is an intensive property, meaning it does not change when the amount of material present in the sample changes. It's a property inherent to the substance itself. Cutting the PlayDough simply changes its shape and size, but not its density, as density is the ratio of an object's mass to its volume. So, whether it's a large piece or two smaller pieces if the material is the same, the density does not change.
