In order for our bodies to gain energy we must digest foods to fuel our bodies. That energy comes from foods and drinks that we consume everyday. The meals that we eat go through the digestive process and nutrients are carried out throughout the whole entire body to help our bodies function. The law of conservation of energy states that energy is neither created nor destroyed, in order for that to be true for example in eating we wonder where the energy goes.
In digestion where most of the digestion occurs is in the small intestines. This is where sugars, amino acids and fatty acids are absorbed into the villi. The villi then releases the soluble nutrients into the body system where the energy that came from foods are used but not destroyed. To prove that no energy is destroyed, the large intestines absorbs unusable, indigestible wastes and then eliminated from the anus which gets rid of energy that could not be used. The energy that is not used is excreted not destroyed. .
Chemistry is all around us, even when we eat and when we use lots of energy during sports to fuel our bodies. The energy is being used but not destroyed, the law of conservation can be applied to mostly everyday actions that people do. We all use some source of energy and we wonder what happens to it and by the wonders of modern chemistry we can understand apply the law of conservation of energy. .
These include: solar energy, wind energy, and hydroelectricity. ... Solar Power, hydroelectricity, and wind energy are all methods of renewable energy sources. ... Solar energy is in essence getting energy from the sun. ... In many cases, wind energy is an ideal power solution. ... Most of the petroleum bi-product is used to produce energy. ...
Energy is a vital part of life. Energy is so important that it makes me think what is the future for energy. ... Wind power and solar energy are two ancient energy sources that have benefited from developments in modern technology. Wind energy is a widely available resource. ... The sun is another means by which we can attain energy. ...
There are two types of energy, Potential Energy and Kinetic Energy. Potential energy is the capacity to do work. Kinetic energy is the total amount of work that is done. ... The producers then use this energy as a form of food. ... ATP is an energy carrier; it transfers some energy to metabolic workers and is formed by aerobic respiration. ...
Energy Supply and Demand Energy supply is the total amount of usable energy available to people for doing work. ... Heat energy is the most commonly used form of energy. Energy may be obtained directly from an energy source, as when people burn wood to produce heat. ... The rapid growth of energy use endangers the world's supply of energy. ... Conserving energy and using it wisely will also make the energy supply last longer. ...
Senior Project: How to build an energy efficient house Technology advances on a daily basis. To make these advances the technology needs to be fueled by a form of energy. ... Homes are one of the largest energy consuming units known today. ... Energy prices have been so erratic over the past few years" people are always looking to save money when it comes to energy. I have researched energy efficiency and now I will explain what I have discovered and what I would use to build my energy efficient house. ...
Conservation of Energy Objective: The objective is to find the spring constant, and to find the potential energy of the system. ... The data indicated for the mechanical energy is conserved for this system. ... Another purpose of the lab was to study the effect of conservation of energy. ... Equations for both gravitational and spring potential energy were used. The low percent error between the two values proves that the energy is conserved. ...
The third type is the more efficient use of energy; adjusting to higher energy costs. ... Increased energy efficiency helps the world energy balance and productive conservation is no less an energy alternative than the energy sources. ... Low energy prices make it difficult to convince people to invest in energy efficiency. ... High-energy prices in the 1970s started efficient energy use in constructing buildings and houses. ... Energy is the basis of industrial civilization; without energy, modern life would cease to exist....
It is the energy created in this reaction that powers the car. ... Geothermal energy is a huge source of energy that is clean and reliable. ... Flowing water has a lot of energy. People over the years have developed ways to harness the kinetic energy and convert it into mechanical energy, then electrical energy. The most common way to harness the energy is by use of a dam. ...
