4. If an object has a density of 0.8 g/cm3, will it float or sink in water?

Answers

Explanation:

Substances with their density less than the density of water which is 1 g/cm³ will float on it whiles those greater than that of water will sink into the water.

From the question the density of the object is 0.8 g/cm³

Since it's density is less than that of water the object will float on water .

Hope this helps you

Final answer:

An object with a density of 0.8 g/cm3 will float in water because its density is less than the density of water, which is 1 g/cm3.

Explanation:

The question is asking whether an object with a density of 0.8 g/cm3 will float or sink in water. Floating and sinking are determined by the principle of buoyancy, which depends on the density of the object compared to the fluid (in this case, water) it is placed in.

Water has a density of 1 g/cm3. So, if the object's density is less than 1 g/cm3, it will float, if it's more it will sink. Since 0.8 g/cm3 is less than 1 g/cm3, an object with this density will float in water.
