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

Answer: The density of an object is the mass of the object divided by its volume.

Remember that mass of an object is the amount of matter that the object contains. The unit for mas in the standard international unit system is the kilogram (kg), which is 1000 grams; the unit of mass in the US is the pound (lb), which is 453.592 grams.

The volume of an object is the amount of space that the object occupies. The unit for volume in the standard international unit system are the cubic meter () and the liter (L); 1 cubic meter equals 1000 liters.

The density of an object is the quantity of mass of the object per unit of its volume. The unit for mas in the standard international unit system is the kilogram per cubic meter ().

Now, lets create our hypothesis:

If the mass and the volume of and object are known, then its density can be calculated dividing the object's mass by its volume.

We can conclude that the density of an object can be obtained by dividing its mass by its volume.

Answer 2

Answer:

Sample Response:

Explanation:

If the mass and volume of an object can be measured, then its density can be determined because density equals mass over volume.

"things you should check if your paragraph has this"

the “if” part of the hypothesis refers to mass and volume.

The “then” part of the hypothesis refers to the calculation or determination of density.

The “because” portion of the hypothesis connects the property of density as characteristic of an object or substance.
