A block of aluminum is heated electrically by a 25 W heater. if the temperature rises by 10°C in 5 minutes, the heat capacity of the aluminum is?
A
850 JK-1
B
750 JK-1
C
650 JK-1
D
500 JK-1
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Heat supplied = Heat gained
P x t = C ∆ Ø
(25 x 5 x 60)/10 = 750 JK-1
