Converting Energy

1 The Law of Conservation of Energy states that energy can neither be destroyed or created, only transferred or transformed. That being said, each form of energy has the ability to be converted into another form of energy. And since there are several forms of energy, that makes many different conversions achievable. Almost all technological gadgets convert one energy form into a new one. The vast number of devices that can convert energy into other states of energy are termed transducers. A few types of transducers are antennas, Geiger-Müller tubes, microphones and even the human ear.

Many kinds of energy are used to do a wide variety of physical work. Radiant energy such as solar power takes energy from the sun and can transfer it into thermal energy to warm up someone’s body. Or it can convert into electrical energy to power a home. Batteries go from chemical energy into electrical energy that can power up toys, electronics, watches, and even cars. And even potential energy, the energy stored in everything when at rest can be transformed into kinetic energy when those objects are in motion and are using their stored energy.

Fossil Fuels

2 Fossil fuels are created from natural resources, for instance deceased creatures buried underground for millions of years. And because it takes such a long time for fossil fuels to form they are considered non-renewable resources. Types of fossil fuels include petroleum, coal and natural gas. These fuels account for over 90% of the world’s energy utilization and growing. This is a problem for the earth since burning fossil fuels releases carbon dioxide and other gases into the air; which is contributing to global warming. Plus coal mining can be very hazardous ...

    Water Turbine: water turbine is used to convert energy from one form to another. When water falls on buckets it helps to rotate the turbine.When water falls it has kinetic energy so kinetic energy is converted into potential energy to run turbine. Turbine is connected with generator.Energy produced by the turbine is mechanical,so generator converts mechanical energy into electrical energy. There are two types of turbines Impulse turbine Reaction turbine Impulse turbine: In this type of turbine

    Hypertension is one of the major risk factors for the development of cardiovascular diseases including stroke and may also have a role in the development of vascular cognitive impairment and vascular dementia [1, 2]. Angiotensin I-converting enzyme (EC 3.4.15.1; ACE) plays an important role in the rennin-angiotensin system and it is a carboxyl-terminal dipeptidyl exopeptidase that catalyzes the conversion of angiotensin I to angiotensin II [3-6]. ACE converts an inactive form of decapeptide, angiotensin

    photosynthesis will be larger. Plants can absorb and use light energy because they have a green pigment, chlorophyll, contained in the chloroplasts in some of their cells. Chlorophyll allows the energy in sunlight to drive chemical reactions. Chloroplasts act as a energy transducers, converting light energy into chemical energy. So as the plant has more light the chlorophyll inside the chloroplasts can react faster absorbing in more light for food and energy. The equation for photosynthesis can help to predict

    Thermodynamics can be defined as the science of energy. Although every body has a feeling of what energy is, it is difficult to give a precise definition for it. Energy can be viewed as the ability to cause changes. The name thermodynamics stems from the Greek words therme (heat) and dynamics (power), which is most descriptive of the early efforts to convert heat into power. Today the same name is broadly interpreted to include all aspects of energy and energy transformations, including power generation

    The link between the number of carbon atoms in a fuel with the amount of energy it releases Alcohols generally belong to compounds whose molecules are based on chains of carbon atoms. They usually contain one oxygen atom, which is joined to a carbon atom by a singular bond. This makes them different to other compounds. The oxygen atom is joined to the hydrogen atom as well as the carbon atom, which makes the oxygen a part of a hydroxyl group. These atoms are generally a part of a hydrocarbon chain
