An amount of ice of mass $10^{-3}$ kg and temperature $-10^\circ C$ is transformed to vapor of temperature $110^\circ C$ by applying heat. The total amount of work required for this conversion is,
(Take, specific heat of ice = 2100 J kg $^{-1}$ K $^{-1}$ ,
specific heat of water = 4180 J kg $^{-1}$ K $^{-1}$ ,
specific heat of steam = 1920 J kg $^{-1}$ K $^{-1}$ ,
Latent heat of ice = $3.35 \times 10^5$ J kg $^{-1}$ ,
Latent heat of steam = $2.25 \times 10^6$ J kg $^{-1}$ )
