PLEASE ANSWER B A friend of yours receives a bag of rare coins for their birthday and boasts that one of the coins is pure silver. You decide to test this theory by conducting a simple experiment in which you construct a coffee cup calorimeter. You fill the calorimeter with 55.5g of water at 16.5°C,heat the 15.5 g “silver” coin to 100.0°C, anddrop it in to observe the change in temperature. The final temperature in the calorimeter reads 22.0 °C. a)If the specific heat of silver is known to be 0.240 J/g°C, do your findings support or refute your friend’s claim? Support your answer with a calculation. b)How would thefollowing results change if you were to double the amount of water used in the experiment? Please support your answer with equations as necessary. You need not do any calculations. a.The temperature change of the water. b.The specific heat of the metal.
