Question
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 69.06 grams of nickel to 98.08 °C and then drops it into a cup containing 85.36 grams of
water at 21.21 °C. She measures the final temperature to be 27.45 °C.
The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a
separate experiment to be 1.65 J/°C.
Assuming that no heat is lost to the surroundings calculate the specific heat of nickel.
Specific Heat (Ni) =
J/g°C.
