Question

the volume of 40 g of a solid is 15 cm^3 . If the density of water is 1 g /cm^3.will the solid float or sink.

Answer 1

volume = 15 cm cube. Mass = 40 g

Density of solid = mass/volume= 40 / 15 = 2.7(approx)

Since , the density of solid is more than water. Therefore it will sink.

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= 40 g

Volume of sub., V= 15 cm^3

density of the substance

= M/V

=40/ 15

= 2.6 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______❤
