To determine the specific heat of an object, a student heats it to 100 ∘C in boiling water. She then places the 63.7 g object in a 170 g aluminum calorimeter containing 111 g of water. The aluminum and water are initially at a temperature of 19.6 ∘, and are thermally insulated from their surroundings.
If the final temperature is 22.7 ∘, what is the specific heat of the object?

A student heats 64.73 g silver to 97.71 °C and carefully lowers it into a cup containing 78.69 g water at 23.26 °C. She measures the final temperature to be 26.46 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.76 J/°C. Assuming that there is no heating of the surroundings calculate the specific heat capacity of silver.

In the laboratory a student determines the specific heat of a metal as follows: He heats 18.4 grams of tungsten to 98.08 °C and then drops it into a cup containing 77.7 grams of water at 21.47 °C. When thermal equilibrium is reached, he measures the final temperature to be 22.03 °C. Assuming that all of the heat from the metal is transferred to the water, he calculates the specific heat of tungsten to be J/g°C.
