How much energy (heat) is required to convert 248 g of water from 0oC to 154oC? Assume that the water begins as a liquid, that the specific heat of water is 4.184 J/g.oC over the entire liquid range, that the specific heat of steam is 1.99 J/g.oC, and the heat of vaporization of water is 40.79 kJ/mol.
Make a table:
1) to heat water to 100C
2) to change water to steam at 100C
3) to heat steam from 100C to 154C
figure all three of those, and add.
I will be happy to critique your thinking.
