Natural disasters are often not natural disasters‚ but are in fact human disasters. Discuss this statement in relation to seismic events. The word ‘natural’ indicates that humans have not caused the disaster. However‚ human activity can certainly interfere with nature‚ which in turn may either cause a natural disaster or make its effects much worse. Earthquakes can affect people in many different ways in countries all over the world. They are a product of intense seismic activity where plates are

thought of how your heart beats everyday tirelessly without stopping and how it pumps blood throughout the body? Well here is how it works.. Psychological Orientation:. As I started researching information about the different functions of the heart‚ I realized I didn’t know much about how our heart really works and why is it important to our body. So‚ I did significant research to educate myself. Logical Orientation: As students many of us have to know the basic stuff on how our body works with this

Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than

How a Microwave Works By Zach Betten [pic] What is a Microwave? A microwave oven or microwave is a kitchen appliance that cooks or heats food by using electromagnetic waves. This happens by using microwave radiation to heat materials such as water and other things within the food. This leads to food being more evenly heated throughout. Basic microwave ovens heat food quickly and efficiently. One setback is that they do not brown or bake food in

GAS LAWS Properties of Gases Gases expand into any available volume • gas molecules escape from open containers. Gases are completely miscible • once mixed they will not spontaneously separate. Gases are described in terms of T‚ P‚ V and n Volume‚ Amount and Temperature • A gas expands uniformly to fill the container in which it is placed – The volume of the container is the volume of the gas – Volume may be in liters‚ mL‚ or cm3 • The temperature of a gas must be indicated

English 1023---M02 28 October 2012 Gas Prices Today‚ gas price as a national average have risen to 2.1 dollars per gallon. This is the highest gas price increase since 1990‚ during operation desert storm. What is the cause of this drastic increase in gas prices? Limited supply of crude oil from the Middle East some say. Others think the cause is high trade tariffs on incoming foreign oil. But what is the solution to this problem? Is it drilling in our national wildlife reserves in Alaska? Dropping

Gas Laws Name Institution The 3 Gas Laws Introduction The three gas laws include: Gay-Lussac’s law‚ Boyle’s law and Charles’ law. When combined with Avogadro’s law the three laws can be generalized by the ideal gas law. Gases possess observable properties which include‚ mass‚ pressure (P)‚ thermodynamic temperature (T) and volume (V). These properties are related to each other and the state of a gas is determined by their values. The three laws are derived from these properties. Discussion

GAS CHROMATOGRAPHY EXPERIMENT The purpose of this experiment is for the student: 1) to learn the general theoretical aspects of gas chromatography as a separation method‚ 2) to learn how to operate gas chromatographs specific to COD‚ 3) to become familiar with using the gas chromatograph (GC) to qualitatively identify components of mixtures‚ 4) to be introduced to and to interpret the quantitative data available via gas chromatography‚ 5) to gain insight into how the GC technique is used

How an SCR works?-Principle of Operation SCR Working Principle The SCR is a four-layer‚ three-junction and a three-terminal device and is shown in fig.a. The end P-region is the anode‚ the end N-region is the cathode and the inner P-region is the gate. The anode to cathode is connected in series with the load circuit. Essentially the device is a switch. Ideally it remains off (voltage blocking state)‚ or appears to have an infinite impedance until both the anode and gate terminals have suitable

Do Gas Stations cause soil pollution? Soils are extremely important parts of every ecosystem. They are a home to many microbes and provide vital nutrients to the plants that live in them. pH is the measure of acidity or alkalinity of a solution‚ and most organisms have a very small range of pH values in which they can survive. 7 is considered neutral‚ lower than 7 is acidic (lemon juice‚ rain water) and above 7 is basic (bleach‚ soap). Lots of urban areas are dependent on car transportation‚
