Answer to Question #121651 in General Chemistry for Ellen

Question

What is the hypothesis of the lab with the following objectives below?
Objectives:
• Measure the specific heat of two substances: copper metal and an unknown. Using specific heat and the Dulong-Petit constant (value = 25).
• Estimate the atomic weight and compare it with the known atomic weight from the periodic table.
• Measure the specific heat, by performing a laboratory technique called calorimetry, which measures the quantity of heat exchanged between two substances.

Answer 1

The Dulong-Petit limiting law for the specific heats .
