In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction.
A student heats 66.72 grams of nickel to 99.22 °C and then drops it into a cup containing 85.21 grams of water at 21.46 °C. She measures the final temperature to be 27.64 °C.
The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.74 J/°C.
Assuming that no heat is lost to the surroundings calculate the specific heat of nickel.
Specific Heat (Ni) = ___ J/g°C.
