Question

Which of the following constants are needed to calculate the change in enthalpy (
H) for heating a sample of liquid water at 10C to steam at 150C.
I) the heat capacity of water
II) the enthalpy of fusion of water
III) the heat capacity of ice
IV) the enthalpy of vaporization of water
V) the heat capacity of steam

1. II and III only
2. I, II and III only
3. I, II, III, IV and V
4. I and III only
5. I and V only
6. I, II, IV and V only

Answer 1

Did you make a typo in the problem? I don't see any correct answer as written; however, if the 10C actually is -10C, there is an answer.
To change T within a state heat needed is
q = mass x specific heat x delta T.

To change the state at some T the heat is
q = mass x heat fusion/vaporiation depending upon if you are going from ice to liquid water or from liquid water to steam. I would look at

Answer 2

Nope, it was 10 degrees C, which is why I'm stumped. I didn't think any of the answer choices were right, either.

Answer 3

Nevermind, the correct answer was at the top of the next page so I didn't see it.

Answer 4

Thanks for letting me know.
