A) 24g
B) 31.5g
C) 42.5g
D) 22.5g
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 = 22.5gYou need to login to perform this action.
