Steam at 1000C is passed into 20 g of water at 100C. When water acquires a temperature of 800C, the mass of water present will be (Take, specific heat of water = 1 calg-1 0C-1 and latent heat of steam = 540 cal g-1

a
24 g
b
31.5 g
c
42.5 g
d
22.5 g

detailed solution

Correct option is D

Heat lost by system = Heat gained by water Let  m' be amount of heat converted into waterm'×L=mcΔtm'×540=20×1×(80−10)⇒ m'=20×70540=2.5gNow, net mass of water = 20 + 2.5 = 22.5 g
