Chelsea Samatra, Kenneth Ragus Samatra,Ragus 1 Ms. Daligcon Period 4 A Battery That Makes Cents bring up Many coins in the spate depart firebrand the most electrical energy. If in that location argon more than than than coins in the rush, then the more electricity it foundation produce, because the more electrons you have, the more electricity you will get. Batteries are expensive, but you bed induce peerless for exactly 24 cents In this experiment, you will make your avouch voltaic pile using pennies and nickels. In the data, we will hold if the tally of pennies and nickels will affect the number of electric potential and accepted.Problem How many coins in the pile will make the most electricity? Hypothesis If in that respect are more coins, then the more electricity it depose produce, because the more electrons you have the more electricity you will get. Samatra, Ragus 2 Background/ question You might think that batteries are a modern invention, but batteries w ere one of the first ways of making electricity. Alessandro Volta discovered the first electric bombing in 1800. He made a giant stack of alternate layers of zinc, blotting paper soaked in salt water, and silver. This early design for a electric assault and 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 seawater solution. The saltwater solution is called anelectrolyte, and it containsionsin solution from the dissolved salts. An ion is a assort of atoms that carries a domineering or negative electric charge. The ions react with the metals, create anelectrochemical reaction, a special kind of chemical reaction that makes electrons. The dickens 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 electrical say-so di fference, also called potential difference, between the two types of metals. angiotensin-converting enzyme metal becomes positively charged, the positive electrode and the other becomes negatively charged, the negative electrode. This causes electrons to move, creating an electrical livewhich is mea sured in amperes, and then you have electricity In addition, the form for potential difference is current dates exemption or V = I*R, so the formula for current will be voltage divided by resistance or I = V/R.Samatra, Ragus 3 Vocabulary Words * electrochemical Reaction branch of chemistry that deals with the chemical action of electricity and the payoff of electricity by chemical reactions * Electron Also called negatron, an elementary subatomic particle that is a fundamental constituent of matter * Voltaic Pile battery consisting of voltaic cells arranged in series the earliest electric battery devised by Volta. * Electrolyte a liquid or gel that contains ions and buns be decomposed by electrolysis. Materials The materials and equipments that are needed for the experiment are * Pennies (4) Nickels (4) * Mild wait on soap * Vinegar (any kind, 1/4 C. ) * Salt (1 Tbsp. ) * Small subject * Small plate (ceramic, plastic, or Styrofoam not paper or metal) * digital multimeter (any kind that reads mA and mV) Samatra, Ragus 4 * Paper towels (2) * Scissors The procedures for the experiment are 1. In a small bowl, mix together 1/4 C. of vinegar (electrolyte) and 1 Tbsp. of salt (ions). 2. Using scissors, cut 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 some pennies and nickels, wash with a mild detersive (like dish soap), and ironic. 5. Start building your stack on a dry paper towel on your plate. Put down a centime first, then place 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 give the sack with a nickel on top. 6. Attach the leads of the multimeter to the two ends of the battery by touching one lead to the penny on the cornerstone 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 different number of coins. One important rule 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 land of the data table Number 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 above shows that number of coins in the pile had affected the arrive of electricity produced. The viewer can obviously tell that, why? Because the data shows that the more pennies and nickels you have in yoru r 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 image shows the structure of a voltaic pile, which is the first design of a battery thats used 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 made of money work? Since each coin is made up of a different metal, one metal reacts more strongly than the other, which leaves an electrical potential difference (voltage) between the two types of metals.The question is, how will different numbers of coins affect the amount of electricity produced? By making piles with different numbers 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 Amount 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 increase 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 very 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 conclusion, many coins in the pile will make the most electricity, i proved that my hypothesis was repair the more coin s 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 machine-accessible to the research section 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 in truth 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.
