Question

Choose which statements correctly identify the relationship of mass, volume, and density by clicking the sentence.

Answer 1

Explanation:

It is known that density is defined as mass divided by volume occupied by the object.

Mathematically,     Density = $\frac{mass}{volume}$

So, density is directly proportional to mass but density is inversely proportional to volume of a substance or object.

Therefore, with decrease in volume and increase in mass there will occur an increase in density of the substance.

Thus, we can conclude that following given statements are correct.

• Density increases if the volume of an object decrease and the mass remains the same.

• Density increases if the mass of an object increases and the volume remains the same.

• Density remains the same if the mass and volume of an object increases proportionally.

Answer 2

Answer:

Density increases if the volume of an object decrease and the mass remains the same.    true

Density decreases if the mass and volume of an object decrease proportionally.      True

Explanation:

only false statement If the volume of an object increases and the mass remains the same, then density increases
