Calculate the total energy transferred when 200 g of ice cubes at 0°C are changed to steam at 100°C. Specific heat capacity of water = 4200 J/kg °C
Specific latent heat of fusion = 340 kJ/kg
Specific latent heat of vaporisation = 2260 kJ/kg

Explanation:

m = Mass of ice = 200 g

= Temperature change of water =

c = Specific heat capacity of water = 4200 J/kg °C

= Specific latent heat of fusion = 340 kJ/kg

= Specific latent heat of vaporisation = 2260 kJ/kg

Heat required to convert ice to water =

Heat required to raise the temperature of water to boiling point =

Heat required to convert water to steam =

Total heat required

Heat required to convert the given amount of ice to steam at the required temperature is .
