Transcribed Image Text:How much heat is required to change 472 g of ice at -11°C to steam at 106°C?
cice = 2090 J/kg C
c water = 4184 J/kg C
c steam = 2020 J/kg C
Lf = 335,000 J/kg
Lv = 2,256,000 J/kg
Find the heat necessary to turn 8 kg of ice at -8 into water at 11.
c Ice = 2090 J/(kg oC)
c Water = 4187 J/(kg oC)
c Steam = 1996 J/(kg oC)
Lf= 335,000 J/kg
Lv = 2,260,000 J/kg
In order to change some amount of ice
four steps:
• melt the ice into water
heat the water that used to be ice
• boil the water into steam
heat the steam
Which step requires the most heat?
c Ice = 2090 J/(kg oC)
c Water = 4187 J/(kg oC)
c Steam = 1996 J/(kg oC)
