World War 1 was a very different war from all of the other wars previous to it. The number of countries involved in this war was a great deal more than in the preceding wars. There was also more modern technology which made this war different because of the weapons and machinery used. There are a number of different reasons why this war happened‚ but it can be narrowed down to five main reasons that built up tension and therefore started the biggest war in history up until that point in time.

The effect of temperature on a reaction rate In this experiment I shall be investigating how temperature affects the rate of reaction Rates of reaction The Factors that affect the rate of reaction are temperature‚ surface area‚ concentration‚ catalysts‚ light and pressure Surface area – Surface area is the amount of solid surface that is available for reaction - Only affects solids so this will not affect our

1. Introduction The purpose of my project is to demonstrate how water temperature affects the dissolving of sugar in liquid. Everything in our universe is made up of particles which are in constant motion. In a solid state particles move the slowest while in a liquid state particles move the fastest. Under the right conditions‚ solid particles (the solute) when mixed in liquid (the solvent) can form a solution. This occurrence is called dissolving. I wanted to answer the question; does the temperature

The calorimeter was set up as shown in Figure 1 above. A Styrofoam cup was used to line the beaker. Cold distilled water (50 mL) was put into the cup along with a thermometer. Continue writing your procedure (what you actually did‚ not what you were supposed to do) in paragraph format. The list format below is to show an example of how to switch from directions in your lab manual to the formal lab report) 1. Set up the Calorimeter as in Figure 1. 2. Use Styrofoam cup as a liner in the beaker.

Everything Happens for a Reason Leslie Torres English 121 Ms. Rankin November 7‚ 2012 Have you ever heard of “things happen for a reason”? Well I am a firm believer of this quote. I feel like if I didn’t make the choices I did in the past I wouldn’t be here where I am today. Back when I was in high school I made some unwise decisions that caused me to get kicked out of school and be on home studies. Everyone who I thought were my friends never cared to give me a call a text or even send me

They are meant to slow us down‚ keep us safe from dangerous drivers and provides enforcement for the law. However is this nuisance really helping? I think not. The cameras are often inaccurate and ineffective. They also require regular

What Happens to Economy when Government Raises Taxes? Terry Burchett ECO100 Survey of Contemporary Economic Issues Ramzi Salloum July 23‚ 2012 While should the government increases tax rate on everyone as a way to equalize incomes and wealth? It would make it easier for many people and make it fair for the poor and middle class citizens. Government officials that are elected are there to take care of policies and programs. Because when Gross Domestic Product( GPD) taxes increase spending

" Factors affecting the speed of sound in a medium" Type of the medium- The speed of sound is not always the same. Remember that sound is a vibration of kinetic energy passed from molecule to molecule. The closer the molecules are to each other and the tighter their bonds‚ the less time it takes for them to pass the sound to each other and the faster sound can travel. It is easier for sound waves to go through solids than through liquids because the molecules are closer together and more tightly

For this experiment‚ there will be an optimal point for each factor. I believe that the optimal temperature for the enzyme sucrase will be 37°C because that is the point where the temperature increases the rate of reaction to its greatest point without denaturing it. For the pH test‚ I think that the optimal pH for sucrase will be the pH of 7 because it is neutral so it won’t affect the charge in a negative or positive way. For the denaturation test‚ I think that the optimal treatment for the enzyme

new resources appropriately? Are we getting our moneys worth? Bill Gates says we are not and suggests a new model he calls a digital nervous system as a way to maximize value from technology and information. In his book‚ Business @ the Speed of Thought‚ Gates attempts to make the case that most organizations do not get the maximum out of their technology. He asserts that most organizations have the wrong mind-set about how information should be handled and distributed within an organization
