[amp_mcq option1=”Water” option2=”Choloform” option3=”Gasolin” option4=”None of the above” correct=”option2″]
The correct answer is: B. Choloform
Choloform is the most dense liquid from the options given. It has a density of 1.492 g/mL, while water has a density of 1.00 g/mL and gasoline has a density of 0.789 g/mL.
Density is a measure of how much mass is contained in a given volume. It is calculated by dividing the mass of an object by its volume. The density of a substance is an important property because it can be used to identify the substance. For example, if you know the density of a liquid, you can use it to determine whether the liquid is water, gasoline, or another substance.
The density of a substance is also affected by temperature. As the temperature of a substance increases, its density decreases. This is because the molecules of a substance move faster as the temperature increases, and they take up more space.
The density of a substance is also affected by pressure. As the pressure on a substance increases, its density increases. This is because the molecules of a substance are forced closer together as the pressure increases.
