but is actually a form of energy – it is the energy associated with the continual‚ random motion of the atoms which compose macroscopic matter‚ which we can’t see directly. This type of energy‚ which we will call thermal energy‚ can be converted (at least in part) to other forms which we can perceive directly (for example‚ kinetic‚ gravitational‚ or electrical energy)‚ and which can be used to do useful things such as propel an automobile or a 747. The principles of thermodynamics govern the conversion

Physical properties can be seen‚ touched‚ or even measured without the identity of the substance changing. The identity of the substance can be its shape or color. Three physical forms of a substance are solid‚ liquid‚ and gas. Water for example can transform into all three physical forms without its identity changing. The characteristic of water as a shape can be used as an example of a physical property. Water can be frozen into ice‚ vaporized‚ or liquidized. The shape of water as a solid is

Philosophy on Physical Activity I think that being active is an essential part of life that should be developed early. As Americans we are known for being the fattest nation in the world. This is quite heart breaking. But if we help the children now‚ they can take the knowledge that us learned with them for the rest of their lives and hopefully pass it on to the next generation. In physical education the student should be the most important aspect. Physical education should be a student centered

ABSTRACT Food security means to create a condition where enough food is ensured to meet the dietary needs for a productive and healthy life.

Global food crisis is the external reason of food crisis in Bangladesh. There are many more domestic reasons. Over the last three decades rice and wheat production in Bangladesh increased more than double. But‚ as the demand

because even though the opponents state‚ there are alternatives used in multiple laboratories‚ it is important to know whether these are successful. The second question states‚ does the equal amount of physical pain inflicted on animals similar to humans? I ask this question because animals sense physical pain as humans do‚ therefore‚ there must have been a research done to answer this question. Creating different alternatives began in the 1970s through 1980s‚ which resulted to control animal experimentation

EVS ASSIGNMENT PROJECT ON DISASTER MANAGEMENT RESPONSE TO CLIMATE CHANGE WHAT IS CLIMATE CHANGE? Climate change is a long-term shift in the statistics of the weather (including its averages). For example‚ it could show up as a change in climate normal (expected average values for temperature and precipitation) for a given place and time of year‚ from one decade to the next. We know that the global climate is currently changing. The last decade of the

NATIONAL ECONOMIC INTERESTS AS BASE OF ECONOMIC SECURITY The economic security is quite complicated subject of research as it is differently explained in scientific literature. According to V.Tambovtseva‚ for example‚ the economic security is understood as set of conditional properties of its production subsystem‚ providing possibility to achieve the objectives of all system. V.A.Savin considers that the economic security “represents system of protection of important state objectives”. There

It is a paradox that in spite of the advances in technology that we are witnessing today one’s privacy and security of data in the internet is often compromised to a very large extent. Often‚ personal information of individuals is stolen or financial data of companies are whisked away by elements who could put this information to the wrong use.
