Question

Will an object with the volume of 77 grams per cubic centimeter and a mass of 65 gems float or skin in water? Explain

Answer 1

Sink. This is because the density (mass divided by volume) is greater than that of water, and anything that has a greater density than water sinks while anything with a lower density than water floats. Hope this helps.

Answer 2

Answer: The object will float on water.

Explanation:

A substance having more density will sink at the bottom and the substance having less density will float at the top.

We know that:

Density of water = $1g/cm^3$

If the density of object is more than the density of water, it will sink. And if the density of object is less than the density of water, it will float.

To calculate density of a substance, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}$

We are given:

Volume of object = $77cm^3$

Mass of object = 65 g

Putting values in above equation, we get:

$\text{Density of substance}=\frac{65g}{77cm^3}=0.844g/cm^3$

As, the density of object is less than the density of water, it will float on water.
