Cheapest way to manufacture ethanol at hom.

The chemical formula of ethanol is C2H5OH. It is an inflammable liquid, which can be used to generate heat energy. Because of its being combustible, ethanol can be used in ”internal combustion engines” as a substitute to gasoline. Ethanol can be prepared at cheap cost price, that is why using ethanol instead and along with

Types of fuel used in internal combustion engines

Before starting discussing the types of fuels used in internal combustion engines, we, first need to elaborate the types of internal combustion engines and their mechanisms. After having discussed the mechanical features of different types of internal combustion engines, we will find out which types of fuel are used in various types of engine, what

Evolution of Earth

Evolution of Earth’s Atmosphere: The early atmosphere Scientists believe that the Earth was formed about 4.5 billion years ago. Its early atmosphere was probably formed from the gases given out by volcanoes. It is believed that there was intense volcanic activity for the first billion years of the Earth’s existence. The early atmosphere was probably mostly

Evidence of Earth’s layered structure

Evidence of Earth’s Layered Structure Evidence that support the concept of a layered structure of the earth comes from several sources.  First, rock samples taken from great depths do have higher concentrations of Iron and Magnesium in them than average crustal rocs. And second, when the mass and size of the Earth are measured, the

Internal layered structure of Earth

Earth’s Internal Layers The Earth has a layered structure, including the core, mantle and crust. The crust and upper mantle are cracked into large pieces called tectonic plates. These plates move slowly, but can cause earthquakes and volcanoes where they meet. The Earth’s atmosphere has changed over billions of years, but for the past 200 million years it has

Composition and Structure of Earth

Composition and structure of Earth  Earth is a terrestrial planet, meaning that it is rocky body, rather than a gas giant like Jupiter. It is the largest of the four solar terrestrial planets, both in terms of it size and mass. Of these four planets planets, Earth has the highest density, the highest surface gravity

About Earth; the important data

Earth is the third planet from the sun and is the largest of the terrestrial planets in the Solar System in terms of diameter, mass and density. It is also referred to as the World, the Blue Planet and Terra. Home to millions of species including humans, Earth is the only place in the universe

Introduction to Geography and its branches

Geography Geography is the study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources and political and economic activities. In other words Geography is the study of places and the relationships between people and their environments.

Introduction to Information Technology

Information technology is the science associated with the application of computer and telecommunication equipment and accessories to store, retrieve, transmit, transfer, detect, and manipulate data/information. Information technology has developed rapidly in the 20th, and 21st centuries. The term ”Information technology” is synonymously used as the ”computer and its networking”, but it is not confined only

Introduction to Nanotechnology

Nanotechnology: Many superconscious claims may be associated with nanotechnology and expectations for incredible events may be developed, but the uncontroversial point about this technology is, it is the deep scientific study of molecules, atoms, and even their particles. It is a technology of building and manipulation of very tiny devices and apparatus, that nothing can
