Please Answer the problem 3, the red part is the right answer, I just need you write in your own word after you understand it. Thank you~
Step 2: Heat 0°C to 100°C water, Q2 cm1AT (1)(300)(100) = 30000 cal. Step 3: Evaporate 100°C water to 100°C steam, Qs (300) (539) 161700 cal.

Heat is being added to the ice water, so the internal energy of the ice water IS changing. The temperature is a measure of the average kinetic energy per molecule, so if it remains the same, then the kietc energy of the system must also be the same. The increasing internal energy must then be potential energy. This is indeed the case molecules that are "locked" in ice crystals have a low potential energy, and when they are knocked out of their crystal, they have a higher potential energy. In other words, energy is required to break the bonds of the water molecules in the lattice in order to make the liquid. This is where the energy goes into breaking bonds.

When the supplied energy is utilized to increase the internal energy only, the temperature is unchanged, it’s remains the same.
The supplied energy to the substance is useful to break the bonds among the water molecules which were exist in the ice crystal lattice. As heat added to ice water, the internal energy of ice water changes, however the temperature is same, since the average kinetic energy of molecules is same. The increase in internal energy results in increase the potential energy (since the separation between molecules increases).
As molecules knocked out of the crystal, they have higher potential energy. In such a case, the energy supplied to the break the bonds of water a molecule in the lattice is used to turn the crystal from solid state to liquid state.
