A) 2.5 : 1
B) 3 : 1
C) 2:1
D) 1 : 1
Correct Answer: B
Solution :
The latent heat of steam = 540 cal/g and the latent heat of ice = 80 cal/g The specific heat of water is \[1\text{ }cal\text{/}g{}^\circ C\] Heat lost by xg of steam in condensing \[=540x\] ?(i) Heat gained by ice \[=y\times 80+y\times 100=180y\] ?(ii) Equation (i) and (ii) we get \[\frac{y}{x}=3,\] so, \[y:x=3:1\]You need to login to perform this action.
