Explanation:
Explanation:
Given,
I = 5 A
V = 240 V
T = 25 mins = 1500 sec
Now,
Energy dissipated = IVT= 5×240×1500 = 1800000 J
Answer:
change in temperature = (100 - 25) = 75.0°C.
change in thermal energy = mass × specific heat capacity × change in temperature.
= 0.200 × 4,180 × 75.0.
= 62,700 J (62.7kJ)
