A) 24 g
B) 31.5 g
C) 42.5 g
D) 22.5 g
Correct Answer: D
Solution :
Heat lost by steam = Heat gained by water Let M amount of heat converts into water. |
\[m'\times L=ms\,\Delta t\] |
\[m'\times 540=20\times 1\times (80-10)\] |
\[m'=\frac{20\times 70}{540}=2.5g\] |
Now, net water \[=20+2.5=22.5\,\,g\] |
