Ethanol‚ a Fuel? Ethanol fuel is a type of alcohol found in alcoholic beverages that is often made from common agricultural products. It is either mass-produced by fermentation of sugars or from cellulose. Wheat or corn kernels are ground in a hammer-mill to expose the starch‚ the ground grain is then mixed with water‚ heated briefly and enzymes are added to convert the starch to sugar using a chemical reaction called hydrolysis. Yeast is added to ferment the sugars to ethanol and finally the

Investigating the Reactions between Polyvinyl Alcohol and Borax in Making a Rubber Ball Introduction Chemistry‚ while usually thought of as being practiced mostly in labs‚ actually affects everyone‚ everywhere. Chemistry and chemical processes are constantly occurring. We are dependent on them. The air that we breathe‚ the food that we eat‚ and thousands of other simple and confusing things depend on chemistry. In this particular case‚ the relationship between Polyvinyl Alcohol (PVA) and Sodium

What Factors Most Affect Evaporation? Intermediate-Level Science Projects Which Materials Insulate Best Against Windchill? Do Clouds Tell Us What Weather Is Coming? What Factors Most Affect Evaporation? Evaporation of a substance such as water occurs when the molecules in a liquid state absorb enough heat energy to vaporize into a gas. The heat energy‚ which causes the molecules to move‚ is called kinetic energy. The water molecules remain the same during this change‚ except that they’re

Fossil Fuels America’s Dependency on Fossil Fuels America’s Dependency on Fossil Fuels For the past two hundred years the United States depends more on fossil fuels than any other power source. Without fossil fuels‚ the industrial revolution would not have had as much of an impact making United States what it is today. However‚ we as a country are facing very real problems that we must have to address quickly. We are running out of fossil fuels‚ and soon we will not have fossil fuels to power

Various types of Fuel Cells and their working By : Divykant Vishwakarma 03996404910 EEE 2nd shift S.No. 14 Fuel Cell A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel‚ but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air

Introduction Fossil Fuels are the most important energy sources in our world today. The overwhelming majority of the huge amount of energy used in the world comes from the burning of three major fossil fuels: coal‚ petroleum‚ and natural gas. Fossil fuels are a non-renewable source of energy‚ and there is no other . They are formed over a very long period of time; the fossil fuels on earth today were formed from plants and animals that lived up to 300 million years ago. These fossil fuels are found in deposits

Investigating Functionalism Functionalism is a theory about the nature of mental states. According to functionalism‚ mental states are functional states that are defined by their functional roles (causal relations to other things) rather than their intrinsic qualities. To illustrate the difference between the two ways of defining something‚ entities such as clocks (to display time) and calculators (to manipulate numbers) are defined functionally‚ whereas entities such as water (H2O) and gold (Au)

Energy in the form of fossil fuels‚ can it meet all of society’s needs or is it time for us to look at other alternatives before it is too late? The increasing pollution and price of energy has once again ignited the debate about options for future energy. Fossil fuels are hydrocarbon deposits also known as coal‚ crude oil and gas derived from the remains of organic prehistoric plants and animals. They have taken many millions of years to form. Coal is ground to a fine dust when crushed and
