Do now-E transformation and sources worksheet sun How fossil fuel is used as electrical energy: The ___ converts dead organisms into chemical energy which is changed into fossil fuels. Fossil fuels when burned turns water into steam which is then used to generate ___ . electricity
Sources of Energy, pg 729 worksheet 4. Petroleum oil is made from the remains of dead plants who lived in Earth millions of years ago. 6. Natural gas is found when you drill to break up underneath the ground that has these remains of microscopic organisms that lived in Earth millions of years. This in turn releases natural gas for us.
11. Nuclear E of atoms=> Thermal E of water=> KE of steam=>KE of turbine => electrical E out of generator 14. Radioactive waste is sealed in ceramic containers so it wont spill and will not crack during an earthquake.
28. Photovoltaic collectors provide heat by absorbing the Sun’s radiation. Then the heat is pumped into the hot water in the house. 33. A geothermal reservoir is hot water and steam that is trapped under high pressure in the Earth’s surface.
35. The advantage of geothermal energy is an inexhaustible resource. 36. Geothermal plant is powered by using hot water and steam produced by geothermal energy to generate electricity. 39. During the winter the air is cooler than the ground below. Then, the cool water absorbs heat from the ground and releases it into the house.
43. Steps in using Tidal E as the high tide comes in, it turns a turbine connected to a generator to make electricity. stop
