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.

4. 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






5. In everyday situations - the weight of an object is ____________ - which usually makes it acceptable to use the same word for both concepts






6. 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






7. This is the variable that changes as a result of the manipulated variable. The dependent variable is observed and measured. Examples include determining how long various saltwater solutions take to freeze - and determining the number of cycles a pend






8. In each element's square - the ________ is in the middle - the atomic weight is usually directly below the symbol - the atomic number is usually shown at the top of the square






9. A grooved wheel with a rope or other item wrapped around it - used to change the direction of an applied force - change the amount of force - transmit rotational motion - or realize a mechanical advantage in either a linear or a rotational system of






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






11. The number of protons of that element - No two elements have the same atomic number - Elements in the periodic table are arranged in order of increasing atomic number






12. Expand to fill any available space - a compressible fluid - with its volume determined by the pressure and temperature of the environment






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






14. 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






15. Energy taken from finite resources that will eventually dwindle - becoming too expensive or too environmentally damaging to retrieve - Fossil fuels include coal - petroleum - and natural gas - Fossil fuels are limited and nonrenewable and contribute






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






17. Displayed by permanent magnets and around electric currents






18. 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






19. A degree on the Fahrenheit scale is 1/180th of the interval between the __________ and boiling point






20. Elements are assigned atomic numbers equal to the __________ in the nucleus of their atoms - Each element has a different number of protons






21. 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






22. A wave's height - the distance between its resting position and its crest






23. 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






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

26. List the specific materials to be used in the experiment - This allows for replication of the experiment






27. Releases energy when a heavy nucleus splits into smaller fragments - Used in power plants and atomic bombs






28. 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






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






30. Anything that has mass and occupies space - Everything you see and touch is composed of matter






31. 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






32. 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






33. 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
