Question

calculate the heat energy needed to convert 2kg of ice at -12 degree celcius to steam at 100 degree celcius.
specific heat capacity for ice=2100j/kg K
specific latent heat of ice=340000 J/kg
specific latent heat for steam =2260000J/kg


im having issue in solving this question . if anyone knows please do comment

Answer 1

heat the ice to 0 ºC

melt the ice

heat the water to 100 ºC

boil the water

add the energy from all the steps

Answer 2

yes

Answer 3
