how much heat is required to raise the temperature of an aluminium vessel weighing 1.25kg from 25oC to 55oC ? Molar heat capacity of Al is 24 Jmol-1K-1 (atomic mass of Al = 27 u) 

Dear Student,
Given: m= 1.25 kg 
molar capacity= 24  J mol-1K-1
‚Äč

t1= 250C =298K
t2= 550C= 328 K
Q=mct
Q=m×molar capacity×tatomic weight

1.25×24×(328-298)27
Q=  33.33 J
Regards!
