Question

the vol of 40 g of a solid is 15cm.if the density of water is 1g/cm
will the solid float or sink in water ?state reason.

Answer 1

Hi friend ,

Volume of the object = 15 cm^ 3
Mass of the object = 40g
Density of the object = mass/ volume
Density = 40 g/ 15cm^3
Density = 2.66g/cm^3

Since the density of water is 1g/ cm ^3 and the density of the object is 2.66g/cm^3, the object will sink in water because it's density is more than that of water.

Answer 2

Hi there !!!


Mass of the solid is given as 40 grams

Also ,
Volume = 15 cm³


We know that ,

Density = Mass / Volume

= 40 / 15

= 2.66 g /cm³( approx.)

Density of water = 1 g /cm³

For an object to sink , its density must be more than the density of water.

Also , for an object to float , its density must be less than the density of water.


===================================

Here , in this case :

Density of solid is more than density of water.

Hence , the solid will sink.

2.66 g/cm³ > 1 g/cm³
