Explanation:
How much heat is required to convert 0.8 kg of ice at -35°C into steam at 100 C?
Given that:
mass of ice (m) = 0.8 kg = 800 g
Initial temperature () = -35°C = 238 K
final temperature ()= 100°C = 373 K
Specific heat of ice () = 2.108 J/g.K
Specific heat of water () = 4.18 J/g.K
Latent heat of fusion () = 334 J/g.
Latent heat of vaporization () = 2230 J/g.
Total heat (Q) required to increase the temperature of ice from the initial temperature of 238K to final temperature of 373 K is given by the equation:
