A) 23.6g
B) 36.3 g
C) 50.0 g
D) 800g
Correct Answer: C
Solution :
\[q\text{ }=\text{ }ms\text{ }\Delta T\] \[=\text{ }200\,\,\times \,\,4.18\,\,\times \,\,20=16720\text{ }Joule\] \[\because \,\,\,340\text{ }J\text{ }heat\text{ }taken\text{ }by\,\,=\,\,1\text{ }g\text{ }Ice\] \[\therefore \] 16720 J heat taken by \[=\frac{16720}{340}\,\,=\,\,49.17\,\,g\] \[=\text{ }50\,g\]You need to login to perform this action.
