A) 210 s
B) 105 s
C) 420 s
D) 50 s
Correct Answer: A
Solution :
The heat required for producing 1g of steam\[=540\,cal\,=540\,\times 4.2\,J=2268\,J\]. Energy given by immersion heater is =1.08k W = 1080 W Now time taken in boiling 100 g of water \[=\frac{2268\times 100}{1080}=210\,\sec \]You need to login to perform this action.
