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






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






10. A source of electric light that works by incandescence - An electric current passes through a thin filament - heating it until it produces light - The enclosing glass bulb prevents the oxygen in the air from reaching the hot filament - which otherwis






11. The terms gravitation and gravity are mostly interchangeable in everyday use - refers specifically to the gravitational force exerted by the earth on objects in its vicinity






12. 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






13. Multiply force but do not change the direction of the input force End: Fulcrum Middle: Output force Other end: Input force Examples: wheelbarrows - baby strollers - bottle openers






14. 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






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






16. Obtained by two different means - fission and fusion






17. A compressed gas pushes out __________ in all directions






18. 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






19. Form a question (state the problem) - A scientific question is one that can be answered on the basis of evidence and that can be measured - The question often asks - 'What effect will something have






20. This is the one factor that will be intentionally changed during the experiment. Examples include changing the amount of salt that is added to water to determine its freezing point; introducing different soil types in germinating seeds; and changing






21. The resulting piece of paper or solution with water becomes a ________ (one of the oldest) - used to test materials for acidity






22. Collect Data (results) - Analyze the data to look for patterns or trends - Record measurements and observations during the experiment - Present data in a graph - table - or another form






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






24. Refers to various properties of matter in the solid phase that give it a high resistance to its shape changing when force is applied






25. Can multiply force or distance depending on the location of the fulcrum End: Output force Middle: Fulcrum Other end: Input force Examples: seesaws - scissors - pliers






26. Symbol: He Protons: 2 Neutrons: 2 Mass: 4






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






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






29. Height of the bounce of an object dropped o the material - related to elasticity






30. The law of inertia - Without outside forces (such as gravity or friction) - an object at rest will remain at rest - while an object in motion will never stop or deviate from its course

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






32. Scratch hardness - indentation hardness - and rebound hardness






33. Made by combining two or more different materials without a chemical reaction occurring (the objects do not bond together) - They are the product of a mechanical blending or mixing of chemical substances - Either homogeneous or heterogeneous






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






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






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






37. 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






38. 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






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






40. When the electrons flow in one direction - the flowing electricity is referred to as current - An electric current is simply a flow of electrons through a wire






41. When foreign substances are dissolved in water it creates a solution - Solutions with a pH of less than 7.0 are said to be acidic - and solutions with a pH greater than 7.0 are said to be basic or alkaline






42. State the specific plan on how to test the hypothesis - Create a written - step - by - step procedure - Determine the variables (any factor that can change in an experiment)
