Question

The volume of 50 gm of substance is 20 cm3. Does it float in water and in mercury? Explain it.

Answer 1

Mass of substance =50g

Volume of substance =20cm ^3

Density of substance = mass / volume

= 50 / 20 = 5/ 2

Density of water =1 g / cm ^ 3

=5/2×1

=5/2

=2.5

: the substance will sink in water and float in mercury.

Answer 2

_/\_Hello mate__here is your answer--

_______________________

⭐ CONCEPT:-- If the density of an object is more than the density of a liquid, then it sinks in the liquid. On the other hand, if the density of an object is less than the density of a liquid, then it floats on the surface of the liquid.

________________________

Mass of sub. , M= 50 g

Volume of sub., V= 20 cm^3

density of the substance

= M/V

=50/ 20

= 2.5 g/cm^3

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

I hope, this will help you.☺

Thank you______❤
