CSET Physical Science 3

Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The top of a wave's 'hill'






2. Formed by the chemical combination of two or more elements in a fixed ratio Example: water






3. Glass has a higher ___________ than air and the different frequencies of light have different wavelengths (dispersion) - causing them to be refracted at different angles - so that you can see them - The different frequencies correspond to different c






4. Hard matter is ______ with soft matter






5. The north pole of one magnet attracts the ___________ of another - but like poles repel each other - Either pole can attract unmagnetized iron objects






6. Resistance to plastic (permanent) deformation due to a constant load from a sharp object






7. A form of energy that can be used to produce sound - light - heat - and power - it exists where the number of negative electrons does not precisely equal the number of positive protons - Electrons are held in the atom by an electrical force and have






8. The rate of change of position with time v = ?d/?t (velocity = change of distance/change of time)






9. The mechanical advantage of a wedge is given by the ______________________ - Although a short wedge with a wide angle may do a job faster - it requires more force than a long wedge with a narrow angle






10. Other indicators of the ________ of an acid are that when acids react with metals - hydrogen gas is released causing bases to feel soapy when touched






11. Salt has a ___________ than water and therefore doesn't evaporate with the water






12. Involve one substance changing states (not one substance changing into another) - Typically reversible Example: water - Can change from a gas (water vapor) to a liquid (water) to a solid (ice) - but the water molecules do not change






13. A rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object - Examples: wheelbarrow (the wheel works as the fulcrum) - scissors (the fulcrum is where the blades cross)






14. Account for 17 elements in the periodic table - Lack the properties of metals but are very common - Include oxygen - nitrogen - and carbon - 7 metalloid elements - and 7 gases - Poor conductors of electricity






15. A water - soluble mixture of different dyes extracted from lichens - It is often absorbed onto filter paper






16. A compound and portable inclined plane - A triangular - shaped tool used to separate two objects or portions of an object - lift an object - or hold an object in place - It functions by converting a force applied to its blunt end into forces perpendi






17. Heat can be converted to motion - and motion can produce heat






18. Solids - liquids - and gases






19. Composed of only one atom and cannot be separated into different substances except in some instances by radioactive decay or by nuclear reactions






20. Displayed by permanent magnets and around electric currents






21. Atoms are made up of several tiny parts - At the center of an atom is a core called the __________ - which is made up of particles called protons and neutrons






22. The amount of matter in a chemical substance - In everyday usage - is commonly confused with weight






23. Opposite process of nuclear fission - Yields energy when very light nuclei unite to a heavier nucleus - Stars (including the sun) derive their energy from nuclear fusion






24. Electricity flows easily through materials that conduct electricity - Include metals such as aluminum (Al) - iron (Fe) - nickel (Ni) - silver (Ag) - and gold (Au)






25. The particular state of water is determined by ___________ - the behavior of water at one atmosphere (sea level) - freezing at 0






26. In physics and engineering - it means the strength of the gravitational pull on the object (how heavy it is - measured in newtons)






27. Solar - Chemical - Electrical - Magnetic - Nuclear - Sound - Light - Electromagnetic - Mechanical (motion)






28. Lever - Pulley - Inclined plane - Screw - Wedge - Wheel and axle






29. A compressed gas pushes out __________ in all directions






30. A mechanical device that changes the direction or magnitude of a force - The simplest mechanisms that use mechanical advantage to multiply force - Uses a single applied force to do work against a single load force






31. Symbol: C Protons: 6 Neutrons: 6 Mass: 12






32. Kinetic energy: energy possessed by a moving object - An object in an unstable position has potential energy - for the position could be converted into movement Example: a baseball thrown vertically upward






33. Turns red under acidic conditions - and turns blue under basic (i.e. - alkaline) conditions






34. Example of chemical change - Iron chemically reacts with air and water to form rust (ferrous oxide) and is unable to change back to iron






35. Explains why objects appear bent as light passes from one transparent object into another - Light travels at different speeds through different objects (faster through air than through water or glass) - Responsible for rainbows and for the splitting






36. A flat surface whose endpoints are at different heights - resulting in a slope - By moving an object up an ___________ rather than completely vertically - the amount of force required is reduced - at the expense of increasing the distance the object






37. After a rainstorm - the air is full of tiny drops of water - Each drop acts as a prism - splitting the light into the colors of the spectrum






38. For every action (applied force) - there is an equal and opposite reaction

39. A compound composed of one atom of sodium and one atom of chlorine (NaCl - sodium chloride)






40. A constant change in the location of a body - Described by stating an object's position - velocity and acceleration






41. The pitch of a sound depends on how fast the particles of a medium vibrate






42. The rate of change of velocity with time a = ?v/?t (acceleration = change of velocity/change of time)






43. The ability to perform work - _______ transformations result when a change of form takes place - All forms of ________ can be converted into other forms






44. Makes it possible for some elements and compounds to transition from a solid to gas phase without becoming a liquid Example: a block of dry ice (CO2) - which will turn into a gas at room temperature
