100 g of iron shot is placed in a test tube and the test tube is placed in a beaker with 150 ml of water at room temperature. The beaker/test tube combnation is heated until the temperature of the iron metal reaches 100 degrees C. The heated iron metal is poured in to a calorimeter with 100 ml of water at room temperature and the calorimeter is closed. The recorded temperature of the calorimeter is 28 degrees C.
1. Calculate the specific heat of the iron metal.
2. Calculate the atomoc weight of the iron metal.
