KIDS TRIVIA

Detailed explanation-1: -density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

Detailed explanation-2: -We can say that the volume of the object is directly proportional to its mass. As the volume increases the mass of the object increases in direct proportion. The gradient of the graph equals the density of the material.

Detailed explanation-3: -The density of a substance is always defined as the mass per unit volume of that substance. Thus the given statement is true.

Detailed explanation-4: -Density and Volume are inversely proportional to each other. Mass and volume are not the same. Thus, from the above formula, we can say that, For a fixed mass, When density increases, volume decreases.

Detailed explanation-5: -Density can be said as the amount of mass present in a substance for a given volume. Density is the relationship between mass and volume. We can know from the density how tightly the molecules of an object are packed in the available space. The density of the object never changes with size and shape.
