Energy Resource
Energy Resources Unit Test
| Question | Answer |
|---|---|
| Energy | ability to do work |
| Mechanical energy | energy connected to motion or moving objects |
| Heat/Thermal energy | energy involved in the internal motion of particles of matter |
| Chemical energy | energy from the combustion of fuels |
| Electromagnetic energy | energy of magnets, lights and electricity |
| Nuclear energy | energy found in the nucleus, the spliting of atom's nucleus. |
| Kinetic energy | energy of motion |
| Potential energy | energy of shape or position, also stored energy |
| Gravitational potential energy | is potential energy that is dependent upon its height above the Earth's surface |
| Energy conversion | change of energy from one form to another |
| Law of conservation of energy | energy is not created or destroyed, but changes from one form to another |
| Fuel | substance that provides energy as a result of a chemical change |
| Combustion | burning of a fuel to release energy |
| Fossil fuels | energy rich substance that is formed from remains of organisms (coal, oil, natural gas) |
| Reserves | known deposits of fossil fuels that can be obtained using today's technology |
| Petroleum | liquid fossil fuel (oil - black, thick liquid fossil fuel) |
| Refinery | factory where crude oil is separated into fuels and other products |
| Solar plants | structure to collect solar energy to boil water to make electricity |
| Solar cells | a sandwich of very thin layers of silicon to produce electricity from solar energy |
| Hydroelectric power | electricity produced by flowing water (i.e. Niagara Falls Power Plant) |
| Biomass fuels | fuel made from living things |
| Geothermal power | heat from the earths interior |
| Energy conservation | practice of reducing energy use. (i.e. walking instead of driving) |
| Insulation | building material that blocks heat transfer between the air inside and outside. |
| Solar Energy | Heat and Light energy given off by the sun |
| petroleum products | products made from oil (petroleum) |
| Renewable | sources of energy that are able to be used again and again |
| coal | example of a fossil fuel - black, carbon, rock-like |
| Natural Gas | fossil fuel - colorless & odorless (Gas companies add the odor for safety) |
| Name 3 RENEWABLE energy sources: | Solar, hydroelectric, geothermal |
| How do we get energy from Solar energy | solar panels heat up water that makes steam in the power plant, energy can be collected from solar cells |
| How do we get energy from hydroelectric energy | flowing water turn the turbine in a power plant |
| How do we get energy from geothermal energy | magma heats the water in a power plant |
| Be able to label the parts of a power plant | diagram of a power plant (see your notes) |
| Explain the 4 energy conversions in a fossil fuel power plant | explain (see your notes) Think: Chemical, Heat, mechanical & electromagnetic |
| Explain why countries should not be dependant on fossil fuels | Give at least 2 reasons, give details. Think: Takes millions of years to form, using it faster than its formed, U.S. has limited/low supplies, as supply decreases - prices increase |
| Explain ways of conserving eneryg and ways to more effeciently use our resources | Give plenty of details - Think: carpooling, turn lights off, install Energy star appliances |
| A pile of coal that will be used for fuel | Potential Energy |
| A box raised above a person's head | Potential Energy |
| A marble rolling down the hallway | Kinetic Energy |
| A hammer hitting a nail | Kinetic Energy |
| A new car battery | Potential Energy |
| A sixth grader running to Gym | Kinetic Energy |
| School Lunch | Potential Energy |
| eyelash fluttering | Kinetic Energy |
| A mouse trap set with peanutbutter | Potential Energy |
| A slingshot stretched and ready to be let go | Potential Energy |
| Name the 5 forms of energy | 1. Mechanical, 2. Electromagnetic, 3. Chemical, 4. nuclear & 5. heat/thermal |
