Answer 1

Answer #1

Molar specific heat of Copper, c=24.5 J/(mol.K)

Molecular weight of copper= 63.546 g/mol

Thus, 126 g Copper = $\frac{126}{63.546}=1.983$ mol Copper

Temperature increased by $\Delta T$ =2^oC

The amount of heat needed,

$Q= c*(no of moles)*\Delta T=24.5*1.98*2=98J (approximately)$
