8. Brenda was given a ring on her birthday by a friend, who claims that it's made of silver. Brenda questions this, so she takes it to the lab to figure out if it's true. She heats up the 3.5 g ring to 98.4°C, then drops it into a beaker with 24.0mL of water at 24.8°C. After a while, the final temperature of the water is 25.4°C (the specific heat of water is 4.184J/gºC). a. Calculate the specific heat capacity of the metal and show your work. b. Look up the specific heat capacity of silver. Is the specific heat capacity that you calculated the same as the specific heat of silver? 9. A calorimeter has a heat capacity of 8.49 kJ/°C. A banana is completely burned inside, and the temperature increases by 39.8.0°C. a. Calculate how much energy is released by the banana. State your answers in J. b. Find how many calories are in the banana. Assume that 1 Calorie is equal to 4.184 kJ.
