What are some physical properties is most helpful to determine if the liquid is water? A color of liquid
B mass of liquid
C volume of liquid
D boiling point of liquid

D

Explanation: You need to know its boiling point. Aside from knowing the boiling point, you can also check the physical properties of the liquid provided that it is not corrosive. For example, you can check the volume of water, its color, and its smell. You can do the same with the other unknown liquids that you may come across.

where are the choice options?

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
