Chelsea Samatra, Kenneth Ragus Samatra,Ragus 1 Ms. Daligcon item 4 A Battery That Makes Cents snitch Many coins in the pile volition put to work the nearly galvanizingity. If there argon much than(prenominal)(prenominal) than coins in the pile, consequently the more galvanisingal energy it advise produce, because the more electrons you have, the more galvanisingal energy you impart get. Batteries ar expensive, just you burn make ace for on the dot 24 cents In this investigate, you leave behinding make your have voltaic pile exploitation pennies and nickels. In the data, we willing see if the morsel of pennies and nickels will affect the reduce of potential difference and stream.Problem How many coins in the pile will make the most electricity? conjecture If there are more coins, then the more electricity it nominate produce, because the more electrons you have the more electricity you will get. Samatra, Ragus 2 Background/Research You faculty thi nk that batteries are a juvenile invention, but batteries were one of the offset ways of making electricity. Alessandro Volta discovered the first electric barrage fire in 1800. He make a giant circumstances of vary layers of zinc, blotting report card uplifted in season water, and silver. This early design for a battery became known as thevoltaic pile.How does a voltaic pile make electricity? The key to electricity is the movement ofelectrons. In a voltaic pile, electrons move from one metal to the other through the brine settlement. The saltwater solution is called anelectrolyte, and it containsionsin solution from the dissolved salts. An ion is a group of atoms that carries a positive or negative electric charge. The ions react with the metals, ca victimisation anelectrochemical reception, a special kind of chemical reaction that makes electrons. The ii types of metals in a voltaic pile are calledelectrodes.Since there are two kinds of metals, one metal reacts more strongly than the other, which leaves an galvanizing potential difference, too called potential drop, between the two types of metals. One metal becomes positively charged, the positive electrode and the other becomes negatively charged, the negative electrode. This causes electrons to move, creating an electrical realwhich is measured in amperes, and then you have electricity In addition, the pattern for electric potential is on-line(prenominal) times resistance or V = I*R, so the formula for period will be voltage separate by resistance or I = V/R.Samatra, Ragus 3 Vocabulary speech communication * Electrochemical Reaction branch of alchemy that deals with the chemical action of electricity and the issue of electricity by chemical reactions * electron Also called negatron, an elementary particle that is a fundamental constituent of matter * voltaic Pile battery consisting of voltaic cells logical in series the earliest electric battery devised by Volta. * Electro lyte a lucid or gel that contains ions and arsehole be decomposed by electrolysis. Materials The materials and equipments that are needed for the experiment are * Pennies (4) Nickels (4) * Mild dish goop * Vinegar (any kind, 1/4 C. ) * saltiness (1 Tbsp. ) * Small bow * Small shell (ceramic, plastic, or Styrofoam not piece of music or metal) * Digital multimeter (any kind that reads mA and mV) Samatra, Ragus 4 * Paper pass overs (2) * Scissors The procedures for the experiment are 1. In a small bowl, fluff together 1/4 C. of vinegar (electrolyte) and 1 Tbsp. of salt (ions). 2. Using scissors, vitiated up a paper towel into small squares. 3. Place the small squares to soak in the bowl of salt-vinegar solution, and set them aside. 4.Gather whatever pennies and nickels, wash with a mild detersive (like dish soap), and dry. 5. Start build your stack on a dry paper towel on your plate. Put eat a penny first, then can a square of vinegar-soaked paper towel on top, and then add a nickel. Keep repeating the layers until you have a stack of four coins (alternating pennies, wet paper towel pieces, and nickels), making sure you break with a nickel on top. 6. tie the leads of the multimeter to the two ends of the battery by sorrowful one lead to the penny on the bottom and the other to the nickel on the top.Measure the voltage produced by your battery (in millivolts, mV). You can also measure the current produced (in milliamps, mA). Samatra, Ragus 5 7. Repeat the experiment, each time building a battery with a incompatible pattern of coins. One important decree is to always start with a penny and end in a nickel, so the number of layers of pennies and nickels will always match. The translate of the data table quash of Pennies Number of Nickels Voltage (mV) Current (mA) 4 4 6. 8 1. 7 5 5 9. 5 1. 9 6 6 12. 6 2. 1The data higher up shows that number of coins in the pile had affect the derive of electricity produced. The viewer can obviously tell tha t, wherefore? Because the data shows that the more pennies and nickels you have in yorur pile, the more amount of electricity you can produced. The amount of electricity produced on 4 pennies and nickels is 6. 8, why because the resistance was 4 and then the current was 1. 7 and the formula for voltage is V=I*R . The amount of voltage in 5 pennies and nickels is 9. 5 and its current was 1. 9. The amount of voltage in 6 pennies and nickels is 12. and its current was 2. 1. Samatra, Ragus 6 Sample Models This ambit shows the structure of a voltaic pile, which is the first design of a battery thats apply to make electricity. It was discovered by Alessandro Volta in 1800. In this experiment, you will make your own version of the voltaic pile using two different types of coins and a salt-vinegar solution. How does a voltaic pile do of cash work? Since each coin is made up of a different metal, one metal reacts more strongly than the other, which leaves an electrical potential differe nce (voltage) between the two types of metals.The question is, how will different poesy of coins affect the amount of electricity produced? By making piles with different metrical composition of coins and measuring the voltage and current produced, you can test the effect of changing the number of coins in the piles. Samatra, Ragus 7 Analysis issue forth of the Voltage (Pennies Nickels) 30 25 20 15 10 5 0 (4 pennies nickels) (5 pennies nickels) (6 pennies and nickels) The graphs shows that the number of pennies and nickels whether it enlarge or decrease, it will affect the amount of the voltage (mV).The graph above specifically shows and tell us that increasing the number of nickels and pennies will increase the amount of voltage. In a real short way, the more pennies and nickels the more voltage and current. The formula for voltage was V = I * R, so the formula for current was I = V/R and then the formula for resistance was R = V/I. Samatra, Ragus 8 Conclusion In conclusio n, many coins in the pile will make the most electricity, i proved that my hypothesis was castigate the more coins in the pile, then the more electricity it can produce, because the more electrons you have, the more electricity you will get.The data that I made was connected to the research share because the research section, it tells the reader that can the number of pennies and nickels will affect the amount of the voltage? So my data shows that the number of the pennies and nickels did truly affect the amount of the voltage. I will always remember that the more electrons/coins in the pile, the more electricity/voltage it can produced.
