Answer:
the energy used to heat Cu is 27.6 Cal
Explanation:
given data
mass m = 5 g
Specific heat capacity of Cu = 0.092 cal/g
temperature T2 = 80 Celsius
temperature T1 = 20 Celsius
solution
we get here energy used to heat Cu that is express as
Q = m × c × ΔT ....................1
so here m = mass and c = specific heat capacity
and ΔT = T2 - T1
so put value in eq 1
Q = 5 × 0.092 × (80 - 20)
Q = 27.6 Cal
so that the energy used to heat Cu is 27.6 Cal
