Question

1. Cooking oil has a density of 0.526 grams per cubic centimeter (g/cm3). A block

has a mass of 20 grams (g) and a volume of 44 cubic centimeters (cm3).What will
happen when the object is placed into cooking oil? *

Answer 1

The block floats

Step-by-step explanation:

Density is the amount of matter contained in an object compared to its volume. It is the ratio of mass to volume. The SI unit of density is kg/m³. The formula of density is:

Density = mass / volume

An object floats when placed in a liquid if its density is less than that of the liquid and sinks if its density is greater than that of the liquid.

The cooking oil has a density = 0.526 g/cm³

The density of block = mass / volume = 20 g / 44 cm³ = 0.4545 g/cm³

Since the density of the block is less than that of the cooking oil, the block will float when placed into the cooking oil.
