Two Film Cannisters are filled with water. These will be used in Calorimeter. One container will be used for heated pennies and the other for heated nickels. The pennies and nickels will be heated to a temp of 66 C. The cannister that will have pennies dropped into it, has a temperature of 20.1 C and a mass of 15.57g. The cannister that will have nickels dropped into it, has a temperature of 19.7 C and a mass of 17,33g. Two pennies of 2.5g a piece are then dropped in to water filled cannister, the temperature stabilizes at 21.8 C. Next, two nickels at 5g a piece are dropped into the other cannister, the temperature stabilizes at 22.8 C.

What is the heat capacity of the coins?

What is the specific heat of each coin?

How much thermal energy did the water gain? How much energy did the coins lose?

Is it possible for two objects to be at the same temperature but have different amounts of heat in them?

Which has the greater heat capacity: the water or the pennies?

Solutions

Expert Solution

Heat = mass × specific heat × temperature

so if two objects are at same temprature they can have different amount of heat depending on the mass and material of the object.
