Question1. Which of the following is least likely be categorized as “science”? Determining the qualities of a pigment used in a famous painting Determining the age of the marble used to make a famous statue Determining the aesthetic properties of a famous poem Determining the thickness of paper on which a work of Shakespeare was written Question 2. You notice that when the parchment paper of an ancient document is exposed to a certain chemical, the parchment paper becomes a different color. What have you done? used reason and the insight of your mind relied on received wisdom performed an experiment made an observation Question 3. Which of the following is NOT out of place in the context of the scientific method? Strong reluctance to ever change a hypothesis Preconceptions affecting one’s observations Seeking irrefutable proof of one’s ideas Addressing questions with an open mind Question 4. A scientific observation must be which of the following? Supportive of the hypothesis in question Previously unobserved Reproducible Unique Question 5. Kepler’s first law of planetary motion says: Planets orbit the Earth along elliptical paths. Planets orbit the Sun along elliptical paths. Planets orbit the Sun along circular paths. Planets orbit the Earth within crystal spheres. Question 6. Vectors are quantities with which of the following properties? Magnitude. Magnitude or direction Direction Magnitude and direction Question 7. The measurement of how velocity is changing over a period of time is called: Acceleration Velocity Speed Distance Question 8. Which of the following is the best definition of energy? The ability to do work The amount of work in an object The measure of the force in an object The size of the force acting on an object Question 9. Which of the following is NOT a kind of potential energy? Electrical Elastic Thermal Magnetic Question 10. When a group of organisms get all their energy from the same source, we refer to them as: an ecological niche. a tropic level. a natural biome. an ecological system. Question 11. In science, heat is commonly measured in what unit? Calorie Degree Specific heat capacity Gallon Question 12. The coldest possible temperature—absolute zero—is which of the following? 0oC -460oF -273oC 0K Question 13. Which one of the following is NOT a statement from the Second Law of Thermodynamics? Heat will not flow spontaneously from a cold to a hot body. Every Isolated system becomes more disordered with time. Living things must be able to absorb heat from their environment by radiation. You cannot construct an engine that does nothing but convert heat to useful work. Question 14. Which of the following is something common to both the electrical force and the gravitational force? They both have roughly the same relative strength. They both can only cause attraction between objects. Both of these are common features between the forces due to electricity and gravity. Neither of these are common features between the electrical and gravitational forces. Question 15. When electric charges are in motion, we have: a voltage. a battery. a wire. an electric current. Question 16. An electric motor does which of the following? Converts heat into electrical energy and mechanical energy. Converts mechanical energy into electrical energy and heat. Converts electrical energy and heat into mechanical energy. Converts electrical energy to mechanical energy and heat. Question 17. One significant difference between matter waves (such as earthquakes and sound waves and water waves) and electromagnetic waves is which of the following? Matter waves happen on larger scales. Electromagnetic waves don’t have detectable effects. Electromagnetic waves can travel through nothing at all. Matter waves involve some type of up-and-down motion. Question 18. The nature of an electromagnetic wave is that: the electric field is parallel to the magnetic field and both are perpendicular to the direction of propagation. the electric field is perpendicular to the magnetic field and both are perpendicular to the direction of propagation. the electric and magnetic fields are parallel to each other and to the direction of propagation. the electric and magnetic fields are perpendicular to each other and the electric field is parallel to the direction of propagation. Question 19. The most energetic kind of electromagnetic radiation is which of the following? Infrared waves Microwaves Gamma rays X-rays Question 20. If you use an electrical current to break down water, you get what two gases? hydrogen and oxygen carbon and dioxide carbon and oxygen hydrogen and carbon Question 21. How is the organization of the Periodic Table of Elements related to the number of electrons in the outermost shell of atoms? Within a given row, all electrons are within the same shell. The electrons within elements in the leftmost column fill the lowest energy shells. A different column in the Periodic Table corresponds to a different shell. A different row in the Periodic Table corresponds to a different shell. Question 22. In the Rutherford model of the atom, electrons would not stay in orbit very long because they would spiral down into the nucleus. Yet, the Rutherford Model is similar to the planetary model of the solar system. Why don’t the planets spiral down into the Sun? The gravitational force is much, much weaker than the electrical force so the effects virtually non-existent. Because the planets and Sun are much larger than electrons and a nucleus. Unlike the gravitational force, the electrical force between two objects increases with their separation. Unlike electrons, planets are not accelerating and therefore don’t emit energy in the form of radiation. Question 23. When two atoms link up we call that: periodicity. a chemical bond. a noble gas. valence. Question 24. Because of the distribution of electrical charges in metals, metals tend to be: malleable. dull (not shiny). electrically non-conductive. undesirable for industrial purposes. Question 25. The covalent bond is like the ionic bond because of _________, and it is like the metallic bond because of __________. the sharing of electrons; the many atoms involved the relatively few number of atoms involved; the sharing of electrons the transfer of electrons from one atom to another; the many atoms involved the few number of atoms involved; the transfer of electrons
