Question

The volume of 50 gm of a substance is $20c{m}^3$. If the density of water is $1g/c{m}^3$, then the substance will float.

• A. True
• B. False

Answer 1

The correct option is B False

Given the mass of the substance = 50 g
Volume of the substance = $20c{m}^3$

Density of substance = $\frac{Mass}{Volume}=\frac{50}{20}=2.5g/c{m}^3$

Since, the density of the substance $2.5g/c{m}^3$ is greater than the density of water $1g/c{m}^3$, so the substance will sink in the water.
