Test your basic knowledge |

Subject : engineering
Instructions:
  • Answer 40 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. Energy from the sun.






2. The phenomenon whereby the earth's atmosphere traps solar radiation - caused by the presence in the atmosphere of gases such as carbon dioxide - water vapor - and methane that allow incoming sunlight to pass through but absorb heat radiated back from






3. Gas usually found within the vicinity of petroleum reserves.






4. A device that converts light into electricity.






5. Energy produced by mechanical devices - such as gears - pulleys - levers - or internal combustion engines.






6. An energy source that will never run out.






7. Energy stored in the earth in the form of heat.






8. A natural fuel such as coal or gas formed in the geological past from the remains of living organisms.






9. Any significant change in measures of climate - such as temperature - precipitation - or wind - lasting for an extended period of a decade or longer.






10. The unit of energy or work in the MKS system of units - equal to the work done by a force of one Newton - meter.






11. Plant materials and animal waste used especially as a source of fuel.






12. A collection of wind turbines used to create electricity.






13. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.






14. A resource that can be replaced when needed.






15. A resource that cannot be replaced once used.






16. A measure of power equal to one joule of work per second.






17. A result of a force moving an object a certain distance.






18. Oil.






19. The process of controlling resources; for example - limiting soil erosion - reducing sediment in waterways - conserving water - and improving water quality.






20. The use of flowing water from waterfalls and dams to produce electricity.






21. The power of the atom.






22. A system by which electrical power is delivered throughout a region.






23. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.






24. A propeller driven by the wind and connected to a generator. The wind makes it turn the generator - which produces electricity.






25. Energy in transit.






26. The energy possessed by a body as a result of its motion.






27. The ability to do work; types include heat - light - sound - chemical - nuclear - mechanical - electrical.






28. The first and simplest element on the periodic table. It is one of the most common elements in the galaxy.






29. The potential energy locked within a system and released during a chemical reaction.






30. Energy visible to the eye.






31. External surroundings.






32. The rate at which work is performed or energy is expended.






33. The heat equal to 1/180 of the heat required to raise the temperature of one pound of water from 32 degrees Fahrenheit to 212 degrees Fahrenheit at a constant pressure of one atmosphere.






34. Refers to the use of resources in ways that prevent their being depleted or permanently damaged.






35. A unit measure of work.






36. Any source of energy that is limited and cannot be replaced when it is used - such as oil - coal - and natural gas.






37. The flow of electrical power or charge.






38. Energy derived from wind by means of windmills or wind turbines.






39. Energy associated with the flow of electrons.






40. Energy can be neither created nor destroyed. There is a fixed amount of energy present in different forms that can be converted from one form to another - but energy does not go away.
