Determination of the Specific Heat Capacity of a Solid by the Method of Mixtures
Knowing an item's specific heat capacity helps determine its uses, such as a low heat capacity for a soup spoon and a high heat capacity for home insulation. Scholars find the specific heat capacity of a metal ball in the 10th lesson of...
