How many joules does it take to change 127 grams of water from -15 degrees celsius to boiling?

4 steps here. 

1. Energy to heat ice from -15 to 0 degrees.


2. Energy to convert ice to water.


3. Energy to heat water to 100 degrees.


4. Energy to convert water to steam.


So the total energy is about q_1+q_2+q_3+q_4 = 386074,45 J
