Correct Answer - Option 2 : The sealed packet sinks in water.

__CONCEPT:__

**Density**

- The
**ratio of mass to volume of the body** is known as the** density of the material** of the body.

\(\Rightarrow ρ=\frac{m}{V}\)

Where ρ = density, m = mass and V = volume

__CALCULATION__:

Given m = 500 g, V = 250 cm^{3} and ρ_{w} = 1 g/cm^{3}

- We know that the density of the object is given as,

\(\Rightarrow ρ=\frac{m}{V}\) -----(1)

By equation 1 the density of the packet is given as,

\(\Rightarrow ρ_{p}=\frac{m}{V}\)

\(\Rightarrow ρ_{p}=\frac{500}{250}\)

\(\Rightarrow ρ_{p}=2g/cm^3\)

\(\Rightarrow ρ_{p}>\rho_w\)

Hence, option 2 is correct.
