A) (7/8) kg
B) (7/5) kg
C) (8/7) kg
D) (5/7) kg
Correct Answer: C
Solution :
[c] Let x kg of ice can melt Using law of Calorimetry, Heat lost by copper = Heat gained by ice \[2\times 400\times (500-0)=x\times 3.5\times {{10}^{5}}\] or \[x=\frac{2\times 400\times 500}{3.5\times {{10}^{5}}}=\frac{8}{7}kg\]You need to login to perform this action.
