Work Renewable and Non-renewable energy sources &Fuels: Renewable energy comes from natural sources that are constantly and sustainably replenished. The most common renewable energy sources are biomass‚ hydroelectric‚ geothermal‚ wind power and solar power. Sunlight is the source of most renewable energy power; the sun can be used to produce solar energy which is electricity for heating‚ cooling‚ lighting homes and transportation. [1] Non-renewable energy is energy that comes from the ground and

Application of Energy ------------------------------------------------- Forms of energy Main article: Forms of energy Energy exists in many forms: Heat‚ a form of energy‚ is partly potential energy and partly kinetic energy. In the context of physical sciences‚ several forms of energy have been defined. These include: * Thermal energy‚ thermal energy in transit is called heat * Chemical energy * Electric energy * Radiant energy‚ the energy of electromagnetic radiation *

Living organisms catabolize organic molecules within their cells and use the energy released to manufacture ATP by phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve oxidation of foodstuffs‚ yet only the latter requires oxygen. Cellular respiration is a very complex process that consists of many steps that take place inside the cell‚ in an organelle called a mitochondrion

Cellular Respiration Project Objective Answers 1. The overall equation for Cellular Respiration is 6O2 + C6H12O6 6H2O + 6CO2 + energy. Overall‚ it is the reverse reaction of photosynthesis‚ but chemically‚ the steps involved are very different. All you have to do is just flip both sides of the equation of photosynthesis‚ and you have the opposite‚ which is the equation for cellular respiration. They are reversible chemical reactions‚ meaning that the products of one process are the exact

NUCLEAR ENERGY Nuclear energy is the energy contained in the centre ‚ or nucleus of an atom. The nucleus is the most powerful source of energy that exist. Nuclear energy is use in scientific research and in medicine treatments. It powers satellites and submarines‚ and it is used to produce electricity. People have also put nuclear energy to destructive uses through the creation of weapons.1 Nuclear energy also called ATOMIC ENERGY‚ energy

Photosynthesis and cellular respiration play significant roles in existence of all living organisms on the planet. Supplying energy to the cells they carry out is the main process called life. Photosynthesis is the process by which several living organisms such as plants and bacteria utilize sunlight and several raw materials such as carbon dioxide and water to produce sugars and release oxygen into the atmosphere. It does not only supplies oxygen which required for human life but it is also the

Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not

Why does vandalism occur? Vandalism is everywhere‚ why do it? It is stupid and reckless‚ not to mention illegal! It occurs because of bad choices you as a person make‚ like who you surround yourself around and the friends you choose. Or because of the mood or mindset you are in. There are many reasons why vandalism occurs‚ but not many ways to putting it to a stop. Friends are not always your friends! Friends sometimes get you into sticky situations‚ but friends are not the one’s making your choices
