Problems focusing on the thermal behavior of water often involve analyzing its heating curve. This curve graphically depicts the temperature of a water sample as heat is added, illustrating distinct plateaus where phase changes occur (solid to liquid, liquid to gas). Such problems require the application of specific heat capacities for each phase (ice, water, steam) and the heats of fusion and vaporization to quantify the energy involved during temperature increases and phase transitions, respectively. Successfully solving these requires the precise use of formulas such as q = mcT (for temperature changes within a phase) and q = mL (for phase changes). For example, determining the total energy needed to convert a specific mass of ice at -10C to steam at 110C necessitates multiple calculations: heating the ice to 0C, melting the ice, heating the water to 100C, vaporizing the water, and finally, heating the steam.
