Question

state dulong and petit law​

Answer 1

The law of Dulong and Petit states that the product of the specific heat capacity of a solid element and its mass per mole is constant. The value of the constant may be found from the principle of equipartition of energy. Let R be the molar gas constant and T the thermodynamic temperature.

Answer 2

$\bold\red{\underline{\underline{Dulong\:and\:Petit's\:Law:-}}}$

★According to this law, the product of atomic mass and specific heat of a solid element is approximately equal to 6.4.

★The product of atomic mass and specific heat is called atomic heat.

Thus,

Atomic mass x Specific heat = 6.4

or

Atomic mass ( approximate )

= 6.4 / Specific heat

→In above formula , the specific heat must he in cal/g unit.
