The total heat added is obtained as 26.36 kJ.
<h3>What is the heat required?</h3>
We know that heat is the form of energy that exists due to the temperature difference between two bodies. Now when we heat water, we add heat to the water and the effect is that the temperature of the water would begin to rise and this owes to the heat that we have added to the water.
We know from the question that;
Mass of water = 10.0 g
Specific Heat capacity of liquid water = 4.18 J/g*°C
Specific Heat capacity of steam = 2.108 J/g*°C
Heat of vaporization of water = 2260 J/g
H = (10 * 4.18 * (100 - 20)) + (10 * 2260) + (10 * 2.108 * (120 - 100))
H = 3344 + 22600 + 421.6
H = 26.36 kJ
