EXPERIMENT: Specific Heat Capacity of Metals

  DATA TABLE 1:

Object Description –

First Metal

Second Metal

Room temperature, oC

Mass of water in calorimeter, 25 ml = 25 g

Mass of first metal object

Starting temperature of water (room temp)

Starting temperature of object (room temp)

Highest final temperature of water & object

DATA TABLE 2 - Part 1:

Objects

Mass (g)

initial

final

DT

C (cal/g oC)

Water in calorimeter

First metal

Percent error of your experimentally derived value: _____________

DATA TABLE 2 - Part 2:

Objects

Mass (g)

T initial

T final

DT

C (cal/g oC)

Water in calorimeter

Second metal

Percent error of your experimentally derived value: _____________

Questions:

A.Why is it a good idea to start with room temperature water in the calorimeter?

B.Why did we ignore the calorimeter in our calculation, although it is listed in the original equation?

C.When eating apple pie, you may have noticed that the filling seems to be much hotter than the crust. Why is this? What can you conclude about the specific heat of the fillings vs. the specific heat of the crust?

D.Is the heat exchange between the metal and the water in the calorimeter by radiation, conduction or convection? Why?
