QUESTION:
In the nineteenth century two scientists named Dulong and Petit noticed that for a solid element, the product of its molar mass and its specific heat is approximately \(25\ \mathrm{J} /{ }^{\circ} \mathrm{C}\). This observation, now called Dulong and Petit's law, was used to estimate the specific heat of metals. Verify the law for the metals listed in Table 6.2. The law does not apply to one of the metals. Which one is it? Why?
ANSWER:Step 1 of 9
Here we have to find out which metal and why listed in the table 6.2 does not satisfy Dulong and Petit’s law.
