Steam at $100^{\circ}C$ is passed into $20g$ of water at $10^{\circ}C.$ When water acquires a temperature of $80^{\circ}C,$ the mass of water present will be: $\newline$ [Take specific heat of water $= 1$ cal g $^{-1}{}^{\circ}C^{-1}$ and latent heat of steam $= 540$ cal g $^{-1}$ ]

Explanation

To solve this problem, we need to apply the principle of conservation of energy. $\\$ When steam condenses and cools down, it releases heat, which is absorbed by the water. $\\$ Given: $\\$ • Initial mass of water $= 20$ g $\\$ • Initial temperature of water $= 10^{\circ}C \\$
