Questions and Answers
- 1.
The very smallest piece of material that still has the properties of that material is what?
- A.
Element
- B.
Atom
- C.
Crumb
- D.
Dust
Correct Answer
B. AtomExplanation
An atom is the smallest unit of a chemical element that retains the properties of that element. Atoms are composed of subatomic particles such as protons, neutrons, and electrons. They are the building blocks of matter and cannot be broken down further without losing their characteristic properties. Therefore, an atom is the correct answer as it represents the smallest piece of material that still possesses the unique properties of that particular material.Rate this question:

Atoms are made of what three tiny particles?
- A.
Dust, dirt, air
- B.
Protons, electrons, neutrons
- C.
Oxygen, carbon dioxide, water
- D.
Sunshine, food, water
Correct Answer
B. Protons, electrons, neutronsExplanation
Atoms are the basic building blocks of matter. They are composed of three tiny particles called protons, electrons, and neutrons. Protons carry a positive charge, electrons carry a negative charge, and neutrons have no charge. These particles are essential for the structure and behavior of atoms. Dust, dirt, air, oxygen, carbon dioxide, water, sunshine, and food are not the fundamental particles that make up atoms.Rate this question:

True or False. The center of the atom is called the nucleus.
- A.
False
- B.
True
Correct Answer
B. TrueExplanation
The center of the atom is indeed called the nucleus. The nucleus is a small, dense region located at the center of an atom, consisting of protons and neutrons. It contains most of the atom's mass and is surrounded by a cloud of electrons that orbit around it.Rate this question:

Because all atoms are electrically neutral, will they have an equal number of both electrons (-) and protrons (+), or not?
- A.
Yes
- B.
No
Correct Answer
A. YesExplanation
All atoms are electrically neutral because they have an equal number of electrons (-) and protons (+). Electrons carry a negative charge, while protons carry a positive charge. The charges of electrons and protons cancel each other out, resulting in a neutral atom. Therefore, atoms will have an equal number of both electrons and protons.Rate this question:

When protons and neutrons are broken down into smaller particles they are called what?
- A.
Atoms
- B.
Elements
- C.
Quarks
- D.
Microscopic
Correct Answer
C. QuarksExplanation
When protons and neutrons are broken down into smaller particles, they are called quarks. Quarks are elementary particles and are considered the building blocks of protons and neutrons. They are the smallest known particles and are classified into six different types or flavors: up, down, charm, strange, top, and bottom. Quarks combine to form larger particles, such as protons and neutrons, which in turn make up atoms and elements. Therefore, quarks are the correct answer in this context.Rate this question:

Atoms are the smallest particle of material that retains the properties of the material. Atoms are also called what?
- A.
Elements
- B.
Molecules
- C.
Particles
- D.
Sugar
Correct Answer
A. ElementsExplanation
Atoms are the smallest particle of material that retains the properties of the material. Elements are composed of atoms, and each element is made up of a unique type of atom. Therefore, elements are the correct answer because they are synonymous with atoms and represent the fundamental building blocks of matter.Rate this question:

Water has more than one atom. Therefore it is called a what?
- A.
Element
- B.
Molecule
- C.
Particle
- D.
Sugar
Correct Answer
B. MoleculeExplanation
Water is composed of two hydrogen atoms bonded to one oxygen atom, making it a molecule. A molecule is a group of two or more atoms held together by chemical bonds. In the case of water, the atoms are bonded together by covalent bonds. Therefore, the correct answer is molecule.Rate this question:

True of False. Living beings are made up of molecules that are constantly changing.
- A.
False
- B.
True
Correct Answer
B. TrueExplanation
Living beings are made up of molecules that are constantly changing. This is because living organisms undergo various processes such as metabolism, growth, and repair, which involve the constant exchange and transformation of molecules. Molecules within living organisms are constantly being broken down, synthesized, and replaced, allowing for the dynamic nature of living systems. This continuous molecular change is essential for the functioning and survival of living beings.Rate this question:

Can there be a volume, or space, in which there is no matter at all, not even air? Yes. What is it called?
- A.
Partial Vacuum
- B.
Vacuum
- C.
Space
Correct Answer
B. VacuumExplanation
A vacuum is a space or volume in which there is no matter at all, not even air. It is a complete absence of any substance, creating a void or empty space. In a vacuum, there is no presence of particles or atoms, resulting in extremely low pressure. This concept is commonly used in physics and engineering, where a vacuum is created to study the behavior of objects or to prevent unwanted interactions with the surrounding environment.Rate this question:

Term used to measure substance is called what?
- A.
Mass
- B.
Volume
- C.
Density
Correct Answer
A. MassExplanation
Mass is the term used to measure the amount of matter in a substance. It is a fundamental property of an object and is typically measured in kilograms or grams. Mass is different from weight, as weight is the force exerted on an object due to gravity. In scientific experiments and calculations, mass plays a crucial role in determining various properties and behaviors of substances.Rate this question:

How much space an object occupies is called what?
- A.
Mass
- B.
Volume
- C.
Density
Correct Answer
B. VolumeExplanation
Volume refers to the amount of space that an object occupies. It is a measure of the three-dimensional size of an object and is typically measured in cubic units such as cubic meters or cubic centimeters. Mass, on the other hand, refers to the amount of matter in an object, while density is the mass per unit volume. Therefore, the correct answer for this question is volume.Rate this question:

What can be calculated with the mass and volume?
- A.
Mass
- B.
Volume
- C.
Density
Correct Answer
C. DensityExplanation
Density can be calculated with the mass and volume. Density is a measure of how much mass is contained within a given volume. By dividing the mass of an object by its volume, we can determine its density. This relationship is expressed by the equation Mass/Volume = Density. Therefore, density can be calculated using the mass and volume of an object.Rate this question:

Tell me what experiment we did to show a partial vacuum?
- A.
Full soda can in water
- B.
Empty soda can in water
- C.
Plastic bottle in the freezer
Correct Answer
C. Plastic bottle in the freezerExplanation
Placing a plastic bottle in the freezer creates a partial vacuum inside the bottle. As the temperature decreases, the air inside the bottle contracts, creating a lower pressure compared to the outside. This results in a partial vacuum, as the external air pressure pushes the bottle inward. This experiment demonstrates the concept of a partial vacuum by showing the effects of changing temperature on air pressure.Rate this question:
