Web1 nov. 2024 · Dulong and Petit law: The average molar specific heat of all metals at room temperature is constant, being nearly equal to 3R = 6 cal mole –1 K –1 = 25 J mole –1 K –1, where R is gas constant for one mole of the gas. This statement is known as Dulong and Petit law. EXPLANATION: WebAccording to the law of Dulong and petit, the metal bas a molar heat capacity 6 çal/mol.9C„ Hence the atomic weight is approximately 6 30 g/mol u 0.20 Estimate the final temperature dif a system after I f? mol Of an unknown crystalline metal at was immersed in 100 g of water at Ans.
