Question

The volume of 50g of a substance is 20cm cube. If tje density of water is 1g/cm cube ,will the substance float or sink

Answer 1

$\huge\underline\blue{\sf Answer:}$

Substance will sink

$\huge\underline\blue{\sf Solution:}$

$\large\underline\pink{\sf Given: }$

• Mass of Substance (m) = 50g

• Volume of Substance (V) =$\sf{20cm^3}$

• Density of water = $\sf{1g/cm^3}$

$\large\underline\pink{\sf To\:Find: }$

• substance float or sink = ?

━━━━━━━━━━━━━━━━━━━━━━━━━

We know that ,

$\large{♡}$$\large{\boxed{\sf Density={\frac{Mass}{Volume}}}}$

$\large\implies{\sf {\frac{50}{20}}}$

$\large\implies{\sf Density =2.5g/cm^3}$

$\large\red{\boxed{\sf D=2.5g/cm^3}}$

$\large{♡}$Since density of Substance is more then density of water therefore substance will sink.

Answer 2

Answer:

The density of the substance is more than the density of water (1 g cm^−3). Hence, the substance will sink in water.
