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.

8. 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






9. Occurs when light travels only in straight lines - An object is visible because light is reflected from the object into our eyes






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






11. Temperature scale named after the German physicist Daniel Gabriel Fahrenheit (1686-1736) - who proposed it in 1724 - On this scale - the freezing point of water is 32






12. A gas - discharge lamp that uses electricity to excite mercury vapor - The excited mercury atoms produce short - wave ultraviolet light that then causes a phosphor to fluoresce - producing visible light






13. Transferring of heat by the circulating motion of particles (in liquid or gas) - Occurs when hot air is less dense than cool air and therefore rises - When the heat moves in a circular pattern - convection currents are formed - Heat can be transferre






14. A natural phenomenon by which objects with mass attract one another - Compels dispersed matter to coalesce - and thus it accounts for the very existence of the earth - the sun - and most of the macroscopic objects in the universe - Responsible for ke






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






16. The distance between two consecutive points on a wave (crest to crest)






17. A hypothesis is an attempt to answer the question or predict the outcome - - A hypothesis is a possible explanation for a set of observations






18. 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






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






20. If the pressure increases - the volume decreases; the reverse is true as well

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






22. A measure of the acidity or basicity of a solution - The ____ scale is not an absolute scale; it is relative to a set of standard solutions whose pH is established by international agreement - these measurements are important for medicine - biology -






23. The portion of the light that crosses the boundary is - however - deflected in another direction - and the ______ does not equal the angle of incidence






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






25. Transition of heat through a medium - From a region of higher temperature to a region of lower temperature - Heat energy is transferred from one material to another by direct contact - Metals are good conductors of heat






26. Show the number of molecules or formula units of the reactants and products - Example: nitrous oxide is a colorless - odorless gas that causes mild hysteria when inhaled - hence the name laughing gas; it is prepared by heating ammonium nitrate crysta






27. Heat tends to move from a high - temperature region to a low- temperature region - This heat transfer may occur by the mechanisms of conduction - radiation - and convection






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






29. Mechanical advantage of an inclined plane is the ______________ it spans - The inclined plane allows the same work to be done with a smaller force exerted over a greater distance Example: ramp






30. A first - class lever - In its simplest form it consists of a rod attached to a wheel so that their movements are coupled when one of the parts is turned






31. A conclusion is a summary and an explanation of the results of an experiment - Does the data support the hypothesis? If not - a new hypothesis can be formed






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






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






34. Seems to travel in perfectly straight lines as rays - The direction of a ray changes at the interface between two transparent materials - like air and water






35. The ratio of the output to the input force - Also called leverage - Results in less force applied over a greater distance - Helps to make work easier






36. Relies on the the first law - The acceleration of an object is proportional to the force applied (the more force - the more acceleration)

37. A change of one substance into a different substance - Occurs whenever compounds are formed or decomposed - During this reaction - there is a rearrangement of atoms that makes or breaks chemical bonds - This change is usually not reversible - unlike






38. Transferring of heat by emission and dissemination of waves or particles - Generated when heat from the movement of charged particles within atoms is converted to electromagnetic radiation - Electromagnetic radiation emitted from the surface of an ob






39. Energy generated from natural sources (such as sunlight - wind - rain - tides - and geothermal heat) which are renewable (naturally replenished)






40. Scratch hardness - indentation hardness - and rebound hardness






41. Results when electrical charges buildup or increase on the surface of a material - here - there is no current flowing as would be found in electrical outlets - When certain materials are rubbed together - electrons can move from one object to the oth
