Calculate the final temperature for the grams water
50.0 grams of Steam at 125.0 oC.
Specific Heat of Ice = 2.09 J/(goC) = 37.65 J/(moloC)
Let's first get each phase to Liquid water at 0 oC. We can then put energy back in to bring it to the Final Temp.
1. Will the energy to warm the Ice be Positive or Negative?
3. Will the energy to melt the Ice be Positive or Negative?
Group of answer choices
5. Will the energy to cool the steam to 100 oC be Positive or Negative?
Group of answer choices
Group of answer choices
Positive since it is absorbing heat
Group of answer choices
Positive since it is absorbing heat
Positive since it is absorbing heat
Negative since it releases heat
15. Why can we use the Energy steps above even though some of the steps do not really happen (e.g. original water does not really cool to 0 oC)
Group of answer choices
16. Why is the Enthalpy of Vaporization so much greater than than the Enthalpy of Fusion?
