The rule of Dulong and Petit states that the molar heat
capacities of the metallic elements are approximately constant.
Estimate the value of this constant by calculating the molar heat
capacities of the following metals from their specific heats and
taking the average.
Metal | Specific heat J g-1 K-1 |
Molar heat capacity J mol-1 K-1 |
---|---|---|
zinc |
0.388 |
|
copper |
0.385 |
|
zirconium |
0.278 |
Average: _________ J mol-1 K-1
