Did you know that one day in the past the continents were connected with each other? Continental drift states that the continents that we know today were once one large landmass called‚ Pangea. Many people argue with the theory about the continental drift‚ because no one yet has proven to the theory’s idea. Many people have been trying to find ways of how the continental drift could have happen‚ by researching objects from the past. This gave scientist or people another point of view about the continental

6. Applications * Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water‚ but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing

Summary The topic investigated in this report is heat transfer in a concentric tube heat exchanger. A heat exchanger is a device used to transfer heat from a hot fluid to a colder fluid. Heat exchangers are widely used in the petroleum industry for various reasons. Some of the most important reasons are theta heat exchangers increase the process efficiency‚ conserve energy‚ reduce maintenance and provide employee safety among many other reasons. The main objectives of the lab study were to determine

Unit 1 This scheme of work suggests possible teaching and learning activities for each section of the specification. There are far more activities suggested than it would be possible to teach. It is intended that teachers should select activities appropriate to their candidates and the curriculum time available. The first two columns summarise the specification references‚ whilst the Learning Outcomes indicate what most candidates should be able to achieve after the work is completed. The Resources

ocean is what gives us our weather and climate which is known as Atmospheric Circulation/Convection (ETAP‚ 2012). Mechanisms that produce high precipitation in the tropics and temperate latitudes and low precipitation in the tropics The meeting of warm and humid air at the inter tropical convergence zone (ITCZ) from both hemispheres brought by trade winds and the subsequent rise of the air (convection) in the atmosphere. Near the equator‚ from about 5° north and 5° south‚ the northeast

adaptation to varying climatic conditions includes both physiological mechanisms as a byproduct of evolution‚ and the conscious development of cultural adaptations (Harrison et al.‚ 1988; Weiss and Mann‚ 1985). There are four avenues of heat loss: convection‚ conduction‚ radiation‚ and evaporation (Wikipedia‚ 2012). If skin temperature is greater than that of the surroundings‚ the body can lose heat by radiation and conduction. But if

Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport without requiring bulk motion. Thus‚ diffusion should not be confused with convection or advection‚ which are other transport mechanisms that use bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach starting

Internal processes which have been involved in the formation of boxwork weathered rocks. The major internal processes for my surface feature are: 1. The rock cycle and the formation of greywacke. 2. The uplift that brought the rocks from under the ocean up to the shore level. The rock cycle The rock cycle refers to the diverse set of natural processes that lead to the formation and transformation of igneous‚ sedimentary‚ and metamorphic rocks. The rock cycle shows that each type of rock can
