This quiz is about mass, volume, and density. There are 5 multiple choice questions.

• 1.

### How is mass different than weight?

• A.

Mass and wight are not any different. They are exactly the same.

• B.

Mass is the amount of matter and weight is the amount of matter plus electricity.

• C.

Mass is the amount of matter and wight is the amount of matter plus energy.

• D.

Mass is the amount of matter and weight is the amount of matter plus gravity.

D. Mass is the amount of matter and weight is the amount of matter plus gravity.
Explanation
Mass and weight are different concepts in physics. Mass refers to the amount of matter in an object, which remains constant regardless of the location. On the other hand, weight is the force exerted on an object due to gravity and varies depending on the strength of the gravitational field. The correct answer states that mass is the amount of matter, while weight is the amount of matter plus gravity, highlighting the distinction between the two terms.

### You are given a mystery object in science class. Your teacher asks you to determine if your object is more or less dense than water. You place the object in the water and it sinks. What staement would best describe this situation?

• A.

The mystery substance is denser than water.

• B.

Water is denser than the mystery substance.

• C.

They both have the same mass.

• D.

The mystery substance must be hollow.

A. The mystery substance is denser than water.
Explanation
The fact that the mystery substance sinks in water indicates that it is denser than water. Objects with higher density than water tend to sink, while objects with lower density than water tend to float. Therefore, the statement "The mystery substance is denser than water" best describes the situation.

### The formula for finding density is:

• A.

The volume divided by the mass.

• B.

The mass multiplied by the volume.

• C.

The mass divided by the volume.

• D.

The volume multiplied by the mass.

C. The mass divided by the volume.
Explanation
The formula for finding density is the mass divided by the volume. This is because density is defined as the amount of mass per unit volume. By dividing the mass by the volume, we can determine how much mass is present in a given volume, which gives us the density of the substance.

### You have two plastic vials. One contains 40ml of water and the other contains 40ml of alcohol. Which statement is correct?

• A.

Both vials have the same denisty.

• B.

Both vials have the same volume.

• C.

Both vials have the same mass.

• D.

All of the above.

B. Both vials have the same volume.
Explanation
The correct statement is that both vials have the same volume. Density is the mass per unit volume, so even though the vials contain different substances (water and alcohol), their densities may not be the same. The mass of the substances in each vial may also be different, depending on the density of the substances. However, since both vials contain 40ml of liquid, they have the same volume.

### Mass is:

• A.

The amount of matter in an object.

• B.

The amount of matter in a small amount of space.

• C.

The amount of matter plus the volume.

• D.

The amount of matter that makes an object more dense.

A. The amount of matter in an object.
Explanation
Mass is defined as the amount of matter in an object. It is a measure of the quantity of particles (atoms, molecules, or ions) that make up an object. Mass is an intrinsic property and is independent of the object's volume or density. It is commonly measured in units such as kilograms or grams. The correct answer accurately describes mass as the amount of matter present in an object, distinguishing it from the other options which are not comprehensive or accurate explanations of mass.
