The density means that the mass divided by the volume with the formula: density = mass/volume. So volume=mass/density. Under same temperature, the volume=15.5/0.789=19.6 cm3=19.6 ml.

Answer:

Volume of ethanol = 19.6 cm3

Explanation:

Given:

Density of ethanol = 0.789 g/cm3

Mass of ethanol = 15.5 g

To determine:

The volume of ethanol corresponding to the given mass

Formula:

Density of a substance is essentially the mass occupied by it per unit volume

Density = \frac{Mass}{Volume}

Based on the above equation:

volume = \frac{Mass}{Density} =\frac{15.5 g}{0.789g/cm3} =19.6 cm3

3) Egyptians being able to construct such grand structures that still stand (pyramids) serves as evidence that proves Egypt was a very advanced civilization at the peak of their advancement.

Answer:

Physical

Explanation:

because the erosion of the canyon did not change any of the chemical attributes of the rock it only changed the appearance. it may have changed the color which is an example of chemical properties but in this case, it is physical. But in other cases, you would refer to this type of weathering as mechanical weathering.
