A) \[2kg\]
B) \[200g\]
C) \[20g\]
D) \[2g\]
Correct Answer: B
Solution :
Suppose m kg of ice melts then by using \[\underset{(Joule)}{\mathop{W}}\,=\underset{(Joule)}{\mathop{Q}}\,\] \[\Rightarrow \,MgH=mL\Rightarrow 3.5\times 10\times 2000=m\times 3.5\times {{10}^{5}}\] \[\Rightarrow \,\,m=0.2kg=200gm\]You need to login to perform this action.
