Water @ 100kPa and 127 C

Heat added electrically 700kJ/kg

Find final temp using:

a. water table

b. ideal-gas table

c. constant specific heat

2. Relevant equations

Cp = a + bT + cT^2 + dT^3

the constants are also listed in the table

3. The attempt at a solution

by using the superhead water table to find u1 at 2547.618 kJ/kg, I added the 700 kJ/kg and then interpilated to get a final temp of 568 C. This seems correct.

I don't see how one can use the ideal gas tables, and I am at a loss as how to use the constant specific heat to find the final temp. Please advise as how to compute! Thanks
