Final answer:
A) Al
Aluminum (Al) has the highest specific heat capacity among the molecules listed.
Step-by-step explanation:
The molecule with the highest specific heat capacity is:
A) Al
Aluminum (Al) has a specific heat capacity of 0.900 J/g°C, which is higher than the specific heat capacities of the other molecules listed.
Specific heat capacity is the amount of energy required to raise the temperature of 1 gram of a substance by 1°C.
Therefore, aluminum requires the most energy to increase its temperature.
