system not in equilibrium will tend to increase over time. Using water as an example, run-off is a transfer process and evaporation is a transformation process. 1.1.5 Explain the nature of equilibria edit, a steady-state equilibrium should be understood as the common property of most open systems in nature. An open system exchanges matter and energy gcse past english papers aqa
with its surroundings (for example, an ecosystem). Dead organic matter entering a lake is an example of a transfer process; decomposition of this material is a transformation.1.8 Distinguish between flows (inputs and outputs) storages (stock) in relation to systems edit Identify flows through systems and describe their direction and magnitude. In practice, some models require approximation techniques to be used. Feel free to contribute to this book, or ask questions on the discussion page. 1.1.1 Outline the concept and characteristic of systems. Established in 2005, we have jiwaji university phd
many years of experience working with schools and students. Strictly, closed systems do not occur naturally on Earth, but all the global cycles of matter, for example, the water and nitrogen cycles, approximate to closed systems. 1.1.2 Apply the systems concepts on a range of scales edit, the range must include a small-scale local ecosystem, a large ecosystem such as a biome, and Gaia as an example of a global ecosystem. A closed system exchanges energy but not matter; the Biosphere II experiment was an attempt to model this. Positive feedback leads to increasing change in a systemit accelerates deviation, for example, the exponential phase of population growth. Edit, the emphasis will be on ecosystems but some mention should be made on economic, social and value systems and aid the system. Here for a Google Doc version. In contrast, an aquarium may be a relatively simple ecosystem but demonstrates many ecological concepts. A static equilibrium, in which there is no change, should be appreciated as a condition to which natural systems can be compared.(Since there is disagreement in the literature regarding the definition of dynamic equilibrium, this term should be avoided.) Students should appreciate, however, that some. No such systems exist (with the possible exception of the entire cosmos). 1.1.7 Describe transfer and transformation processes edit Transfers normally flow through a system and involve a change in location. Transformations lead to an interaction within a system in the formation of a new end product, or involve a change of state. 1.1.10 Evaluate the strengths and limitations of models edit A model is a simplified description designed to show the structure or workings of an object, system or concept.
