flow towards the cooler end. This will make a gradual increase of temperature at the cooler end until an equilibrium temperature is established. Usually‚ the changes that occur within the bar is not instantaneous and will be different at both end. 2. Radial conduction heat transfer Fluid motion that resulted by force over the surface by an external source‚ such as fans or pumps. Small movement of air is generated which limits the heat transfer rate from the hotter surface to the surrounding air

BORDER-FENCING-A NEEDED NECESSITY OR A WANTED NECESSITY? Many people don’t believe that Border-Fencing is needed‚ while others do feel it is necessary that Border-Fencing be put in place. Border-Fencing is needed due to all the jobs being taken by illegal immigrants. Building the fence would help keep illegal immigrants out and would create jobs.The southern border of the United States is shared with Mexico and spans almost 2‚000 miles. In 2011‚ at a debate over immigration‚ one Republican presidential

King’s major course of action throughout all of his work was nonviolence‚ and he was awarded The Nobel Peace Prize for his work. The war itself was a betrayal of America’s moral obligation‚ heightened by media portrayals of what is just for our nation. King expressed that our spirit continues to diminish as we diminish humanity across the world. His motive was for our populace to stop thinking in terms of our nations as a singular body‚ but to think of our nation as a model “that embraces the brotherhood

Introduction The purpose of this lab is to be able to observe the reaction rates of different chemical substances‚ by looking at which substance is the fastest reactant. This is what chemical kinetics is. Reaction rate is the change in the concentration of a reactant or product in a chemical reaction per unit time. In this lab the requirement was to be able to calculate each Average reaction rate which is the change in reactant or product concentration at a given time interval. Some equations that

Chemistry Lab Report Jeffrey Kenneth Bangero Introduction Firstly we calculated the mass of the beaker and then we put the assigned grams of sodium carbonate and calcium chloride. Then we add 50 ml of distilled water to each substance‚ sodium carbonate dissolved faster than calcium carbonate. After we mixed both sodium carbonate and calcium chloride and they form a solid precipitate. Then we poured it a funnel with a filter paper to get the solid precipitate. Purpose ● The purposed

Chemestry Lab Rates of Reaction (Picture from: http://sciencespot.net/Pages/kdzchem.html) The rate of reaction is how fast or slow a reaction is completed. This is important for factories and chemists all over the world. What happenes during a reaction is atoms or molecules that collide and form new molecules. You can affect this rate of reaction with: temperature of reactants or suroundings‚ surface area of reactants‚ if there is a catalyst present‚ but in theis lab the concentration was changed
