Answer: Option (B) is the correct answer.
Explanation:
Density of a substance is defined as mass divided by its volume.
Mathematically, Density =
So, density is proportional to the mass of substance. Hence, an increase in mass will lead to increase in density of the substance also.
Whereas density is inversely proportional to volume of a substance. Hence, an increase in volume will lead to a decrease in density of the substance.
Therefore, we can conclude that density refers to a physical property that is measured using a ratio of mass divided by volume so that two objects of the same size can still have very different density.

Explanation:
Hello,
In this case, given the heating curve of water on the attached document, we can notice that at 0 °C the solid starts melting, which means that the melting point is reached. Melting point is known as a physical change whereby a solid changes to liquid by the addition of heat as it allows the molecules to separate to each other.
Best regards.
