Energy keeps all living organisms alive, as they need a continual supply of energy to function in order to survive. Some of these processes are continuous such as, metabolism, which is the chemical reactions which occur in the body, these occur by using or releasing energy from chemical substances. Another continuous process which use energy is the transporting of molecules in order for them to break down, and to build new ones. The breakdown of large molecules into their simpler forms to release

Essential Facts for Physical Science Scientific Investigation, Reasoning, and Logic 1. SI (metric) measures, recognized around the world, are a standard way to make measurements. 2. Bar graphs, line graphs, and circle graphs are powerful tools for displaying and interpreting data. 3. To communicate the plan of an experiment accurately, the independent variable, dependent variable, and constants must be explicitly defined. 4. The number of repeated trials needs to be

Plants and Semiconductors A Contrast and Comparison of Energy Conversion J’Haun Egerson Strayer University Photosynthesis is the process used by plants to harness the suns energy. The plants use this harnessed energy to produce food. The leaves of plants help trap the energy from sunlight. The process of photosynthesis transforms the solar energy into the chemical energy of a carbohydrate. Photosynthesis occurs mainly in plant leaves, little to none occurs in the stems, roots, etc. To dive

naturally when humid air experiences a sudden drop in temperature Section 8.1 Air Conditioners Removes some thermal energy but cant make it disappear. It transfers thermal energy from the cooler room air to the warmer air outside Moving Heat Around: Thermodynamics An air conditioner transfers heat against its natural direction of flow. Heat pump- a device that uses ordered energy to transfer heat from a colder object to a hotter object law of thermal equilibrium (zeroth law of thermodynamics)

ENERGY POLICY The energy policy of the United States is determined by federal, state and local entities in the United States, which address issues of energy production, distribution, and consumption, such as building codes and gas mileage standards. Energy policy may include legislation, international treaties, subsidies and incentives to investment, guidelines for energy conservation, taxation and other public policy techniques. Several mandates have been proposed over the years, such as gasoline

Task 3: Discuss the role of energy in the body: Energy can be found in different forms, ways that energy can be found in is through light, kinetic, thermal (heat), sound and chemical. These types of energy are categorised into two which are potential and kinetic energy. Chemical energy is energy that is stored in between the bonds of the atoms and the molecules. They are in between the molecules. Energy comes into our body from all the fats, carbohydrates and proteins that we all consume in
