A) \[31{}^\circ C\]
B) \[22{}^\circ C\]
C) \[19{}^\circ C\]
D) \[15{}^\circ C\]
Correct Answer: B
Solution :
[b] Let the final temperature be T Heat gained by ice \[=mL+m\times s\times (T-0)\] \[=10\times 80+10\times 1\times T\] Heat lost by water \[=55\times 1\times (40-T)\] By using law of calorimetery, \[800+10\,T=55\times (40-T)\] \[\Rightarrow \]\[T=21.54{}^\circ C=22{}^\circ C\]You need to login to perform this action.
