Question

Define the terms

a) Latent heat of fusion of Ice and give its value in J/Kg
b) Latent heat of vaporization of water and give its value in J/Kg

Answer 1

$\mathfrak{\huge{\green{\underline{\underline{Answer :}}}}}$

a) The latent heat of fusion of ice is defined as the amount of heat required to change 1 g of ice from 0to water at the same temperature. For ice, its value is 3.36 105 J Kg-1 in SI-units.

b) The latent heat of vaporization for water is 22.6 x 10^5 J/kg. This means that 22.6 x 10^5 J of heat energy must be added to turn one kilogram of water from liquid to gas at 100 degrees Celsius.
