The detailed answer explains the phase changes of water from ice to steam, highlighting the significance of energy in phase transitions and how it differs from temperature changes.
Heating and Phase Changes of Water: The process starts with heating ice from -15°C to 0°C, then melting the ice, followed by boiling the water. Finally, heating steam from 100°C to 120°C. The energy input required for changing the temperature of a substance without changing its phase is different from that needed for inducing a phase change.
The temperature remains constant during phase transitions like melting and boiling due to the energy being utilized for changing the phase rather than altering the temperature. For instance, it takes significant energy to melt ice into water, much more than raising the temperature of liquid water. This distinction showcases the substantial energy required for phase changes compared to temperature alterations.
