Physical Science- Particle Theory Quiz - Quiz

Matter, as we have come to learn, is anything that has mass and occupies space. Particle theory is a theory of matter that states that a point is made up of small particles that are constantly moving. How well did you understand the topic? Take up the physical science test below and see just how much you know, recall as you refresh your memory.


Questions and Answers
  • 1. 

    Everything is made of matter. Matter is made of...?

    • A.

      Little circles

    • B.

      Air

    • C.

      Particles

    • D.

      Solutes

    Correct Answer
    C. Particles
    Explanation
    Matter is made up of particles. These particles can be atoms, molecules, or ions. They are the building blocks of all substances and are constantly in motion. Therefore, the correct answer is particles.

    Rate this question:

  • 2. 

    Pure substances are substances that...

    • A.

      Are made of only one type of particle

    • B.

      Are made of 2 types of particle

    • C.

      Are naturally occuring

    • D.

      Are man-made

    Correct Answer
    A. Are made of only one type of particle
    Explanation
    Pure substances are substances that are made of only one type of particle. This means that all the particles in a pure substance have the same chemical composition and properties. Examples of pure substances include elements like oxygen and gold, as well as compounds like water and salt. Pure substances can exist in both natural and man-made forms, but what defines them is the fact that they consist of a single type of particle.

    Rate this question:

  • 3. 

    All the particles in a pure substance are...

    • A.

      Identical

    • B.

      Different

    • C.

      Mostly the same

    Correct Answer
    A. Identical
    Explanation
    In a pure substance, all particles are identical. This means that they have the same chemical composition and properties. Whether it is a solid, liquid, or gas, the particles that make up the substance are the same in terms of their atomic or molecular structure. This uniformity allows for consistent behavior and characteristics of the substance.

    Rate this question:

  • 4. 

    When you increase the temperature, particles will...

    • A.

      The speed of the particles stay the same

    • B.

      The speed of the particles increase

    • C.

      The speed of the particles decrease

    Correct Answer
    B. The speed of the particles increase
    Explanation
    When the temperature is increased, the kinetic energy of the particles also increases. This increase in kinetic energy leads to an increase in the speed of the particles. As the particles gain more energy, they move faster and collide with each other more frequently, resulting in an overall increase in their speed.

    Rate this question:

  • 5. 

    Particles are...

    • A.

      Moving only in liquids and gases

    • B.

      Moving only in gases

    • C.

      Moving in solids, and liquids

    • D.

      Moving in solids, gases and liquids

    Correct Answer
    D. Moving in solids, gases and liquids
    Explanation
    Particles in ALL states of matter are constantly moving

    Rate this question:

  • 6. 

    There are spaces between...

    • A.

      Particles in gases

    • B.

      Particles in gases, liquids and solids

    • C.

      Particles in gases, and liquids

    Correct Answer
    B. Particles in gases, liquids and solids
    Explanation
    Particles in gases, liquids, and solids refers to the fact that particles exist in all three states of matter. In gases, particles are widely spaced apart and move freely. In liquids, particles are closer together and can move past each other. In solids, particles are tightly packed and vibrate in place. This answer accurately describes the presence of particles in all three states of matter, highlighting their different arrangements and behaviors.

    Rate this question:

  • 7. 

    Rank in order from smallest to largest, the spaces between the particles in the states of matter...

    • A.

      Gases, liquids, solids

    • B.

      Liquids, solids, gases

    • C.

      Solids, liquids, gases

    • D.

      Solids, gases, liquids

    Correct Answer
    C. Solids, liquids, gases
    Explanation
    The correct order of the spaces between particles in the states of matter is solids, liquids, gases. In solids, the particles are tightly packed together, resulting in the least amount of space between them. In liquids, the particles are still close together but have more space between them compared to solids. In gases, the particles are far apart, resulting in the largest amount of space between them.
