The product of atomic weight and specific heat of any element is a constant, approximately 6.4 . This is known as:

Options

ADalton's law
BAvogadro's law
CNewton's law
DDulong Pettit law

Correct answer

D. Dulong Pettit law

Step-by-step solution

According to Dulong and Pettit's law Atomic weight Specific heat =6.4 (approx) This law is applicable only to solid elements but it fails to explain very high specific heat of diamond.
