You are given an unknown solid substance of mass 1,300 g and you want to estimate its specific heat. Unfortunately, you do not have a thermometer handy. Instead, you throw the substance in a bucket of boiling water. After a while, you remove the substance from the boiling water and put it into a beaker with 400 mL ethyl alcohol at room temperature. Immediately after adding the hot substance into the beaker, the volume scale reads 430 mL. When the alcohol and the substance reach equilibrium, the volume scale reads 429 mL. What is the specific heat of the substance?
a. ≈ 4056.82 J/kg. K
b. ≈ 530 J/kg. K
c. ≈ 470.8 J/kg. K
d. ≈ 1639.9 J/kg. K
e. ≈ 1560.3 J/kg. K
