Question

Write a hypothesis about the use of an object’s physical characteristics to determine its density. Use the format "if . . . then . . . because . . .” and be sure to answer the lesson question "How can the density of an object be determined?”

Answer 1

Explanation:

The density of an object is given by its mass divided by its volume. It is denoted by d or ρ. It is given by :

$\rho=\dfrac{m}{V}$

It the mass and volume of an object is known then it is easier to find its density. It is directly proportional to the mass and inversely proportional to the volume of that object.

If the mass of an object increases, its density will increase because the mass and density are directly proportional to each other.

And if the volume of an object increases, it density will decrease because the volume and density are inversely proportional to each other.    

Answer 2

For this case you must first know the definition of density.
 D = m / v
 where,
 m: mass
 v: volume.
 You can then write the following hypothesis:
 IF you know two physical characteristics of an object then you can determine the density. First weigh the object, THEN measure its volume BECAUSE the density is the quotient between the mass and the volume of an object.
