To determine the specific heat capacity of copper, Alyssa performed an investigation by which she dropped a heated piece of copp
er into a calorimeter. Some of the data Alyssa recorded is given in the following table. The experimental specific heat capacity of the copper is _____J/g°C. Use three significant digits in your answer.

20600Cal
Explanation:
Given parameters:
Mass of water = 319.5g
Initial temperature = 35.7°C
Final temperature = 100°C
Unknown:
Calories needed to heat the water = ?
Solution:
The calories is the amount of heat added to the water. This can be determined using;
H = m c Ф
c = specific heat capacity of water = 4.186J/g°C
H is the amount of heat
Ф is the change in temperature
H = m c (Ф₂ - Ф₁)
H = 319.5 x 4.186 x (100 - 35.7) = 85996.56J
Now;
1kilocalorie = 4184J
85996.56J to kCal; = 20.6kCal = 20600Cal
