You will need the two thermochemistry equations to solve these
More:

You will need the two thermochemistry equations to solve these problems. Have the answers ready in kJ.

You will also need some (but not all!) of these constants:

Specific heat of ice = 2.11 J/(g*K)

Specific heat of water = 4.184 J/(g*K)

Specific heat of steam = 1.97 J/(g*K)

Enthalpy of fusion = 6.01 kJ/mol

Enthalpy of vaporization = 44.07 kJ/mol

1) How much energy does it take to heat 25.0 g of 25.0 °C water to its boiling point? (Assume sea level "normal" value, not the Boone high elevation value)

2) How much energy does it take to boil 25.0 g of water and turn it into steam?

3) How much energy does it take to heat 25.0 g of steam from the boiling point to 150.0 °C?
