Similarly, in the liquid-to-gas transition, molecules need enough kinetic energy to escape the surface tension and enter the atmosphere as vapor. The Role in Environmental Systems On a macro scale, the interaction between solar radiation and the Earth's surface is dominated by phase changes that absorb heat.
How Phase Changes That Absorb Heat Support Environmental Stability
Measuring and Calculating Energy Transfer. In contrast, latent heat—the energy absorbed or released during a phase transition—acts as a hidden reservoir.
This specific thermal energy, which raises the internal potential energy of the molecules without increasing the kinetic energy (and thus the temperature), is known as latent heat. Sensible heat is the energy transferred that results in a temperature change, which is easy to measure with a thermometer.
Phase Changes That Absorb Heat in Natural Stability
This energy intake is why evaporation is a cooling process; the molecules with the highest energy leave the sample, leaving the remaining molecules with a lower average energy and temperature. This buffering capacity is why the temperature of water remains constant at 0°C while ice melts or at 100°C while it boils, creating a plateau on a heating curve that signifies the energy being put to work on the molecular structure.

Looking at Phase changes that absorb heat from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
More perspective on Phase changes that absorb heat can make the topic easier to follow by connecting earlier points with a few simple takeaways.
