HEAT OF COMBUSTION COMPARISON Question: What fuel is the best alternative to gasoline?: CRITERIA 0 points 1 point 2 points ENERGY CONVERSIONS Student's response does not describe how using fuel is a process of energy conversion Student's response partially or incorrectly describes how using fuel is a process of energy conversion Student's response describes how using fuel is a process of energy conversion ENERGY FLOW Student's response does not describe combustion of fuel as either an exothermic or endothermic reaction to explain the flow of energy during the reaction Student's response partially or incorrectly describes combustion of fuel as either an exothermic or endothermic reaction to explain the flow of energy during the reaction Student's response describes combustion of fuel as either an exothermic or endothermic reaction to explain the flow of energy during the reaction HEAT OF COMBUSTION Students response does not describe heat of combustion as it relates to fuel Students response partially or incorrectly correctly describes heat of combustion as it relates to fuel Students response correctly describes heat of combustion as it relates to fuel HEAT OF COMBUSTION COMPARISON Student's response does not compare the heat of combustion of gasoline to that of an alternative fuel or fuels as part of an overall comparison of the fuels Student's response compares the heat of combustion of gasoline to that of an alternative fuel or fuels as part of an overall comparison of the fuels using incomplete or unsubstantiated evidence Student's response compares the heat of combustion of gasoline to that of an alternative fuel or fuels as part of an overall comparison of the fuels using factual and substantiated evidence OTHER COMPARISONS Students response does not compare several other characteristics of gasoline, such as availability, cost, or sustainability, to those of an alternative fuel or fuels Students response compares several other characteristics of gasoline, such as availability, cost, or sustainability, to those of an alternative fuel or fuels using incomplete or unsubstantiated evidence Students response compares several other characteristics of gasoline, such as availability, cost, or sustainability, to those of an alternative fuel or fuels using factual and substantiated evidence Unit 3 Section B Assessment Rubric = Full Points (My Goal)

Solar & Biodiesel Intro. Both of these energy sources make an exothermic reaction. The energy sources that I have chose are both a greater and better resource than Gasoline. Solar and biodiesel help the earth, atmosphere and community all in one. It has some cons in using them but it would make everything for the world a better place to live in. Gasoline may or may not run out one day, but these will not for now. Why not start now before its to late? Also Gasoline pollutes so much of the air and is one of the reasons why our earth is to warm. Using these energy sources would make a better environment and help our earth last. ITS AS SIMPLE AS THAT.

Solar Cars? How can a car work without spending a dime or penny? Solar cars harness energy from the sun converting it to electricity from the sun. Instead of using a battery, some solar cars direct the power straight to an electric motor. The cars can accomplish this through photovoltaic cells. The electricity Combines solar wind and battery Power to run a three passenger car Specifically for city driving. Solar Panels cover its roof and wind Turbine can also catch energy on bluster Days.

More about SOLAR ENERGY The sun has produced energy for billions of years. Solar energy are the suns rays which are called solar radiation that reaches the earth. This energy can be converted into many forms of energy such as heat, and electricity. When it is converted to thermal (or heat) energy, solar energy can be used to heat water for houses, heat buildings, pools, space for inside, green houses, heat other fluids to higher temperatures, to operate a turbine, and to generate electricity. And last the great and main benefits of solar energy are the systems that require the sun do NOT produce air pollutions or carbon dioxides.

Biodiesel Biodiesel is a form of diesel fuel manufactured from vegetable oils, Animal fats, or Recycled Restaurant Greases. It is, safe, biodegrable and produces less air pollutants than petroleum based diesel. Every year the United State spends millions of dollars on foreign oil. People continue to buy products from other countries and spare little money for education, health, insurance, and other important expenses. So why NOT waste money and make our own oil, so all of the United States money don’t just go to waste on oil that just pollutes and hurt our home.

Biodiesel Advantages and Disadvantages Produced from non-petroleum renewable resources. Can be used in most diesel engines, especially newer ones. Less air pollutants. Less green house gases. Non- toxic And safer to handle. Disadvantages Lower fuel economy and power. Currently more expensive. Generally not suitable for use in low temperatures. Impacts on engine durability.
