Find the total heat that is absorbed by 10 grams ice at -10°C to change to steam at 120°C. ( specific heat for ice is 0.4 cal/(g °C), latent heat for melting is 80 cal/g, specific heat for water is 1 cal/(g °C), latent heat for vaporization is 539 cal/g ). Please explain, i am having trouble solving these types of problems, thanks!
