TWO QUESTIONS! 1. What is the purpose of the turbines in coal-fired power plants? A) Carrying electricity B) burning coal C) generating steam D) converting energy 2. Walt listed the steps that occur during the formation of natural gas. Plants and animals that live in a lake die. The dead plants and animals sink to the bottom of the lake. Sand, dirt, and rocks bury the plants and animals. The dead plants and animals are exposed to extreme heat and pressure. Within about twenty years, natural gas forms. Which best describes Walt's mistake? A)

(1) Answers

Turbines area generally located at coal-powered plants in which its primary purpose in the system is to convert thermal energy to mechanical energy which is then transformed into electrical energy for consumption. On the other hand, the mistake that Walt committed would be that it is uncommon for dead remains of plants and animals to be exposed in extreme heat and pressure.
