Answer
Exothermic
Work Step by Step
The process of liquid water turning into ice is an exothermic process. This means that heat is released from the system (water) to the surroundings during the transformation.
When liquid water freezes into ice, its potential energy decreases, since the molecules become more ordered and are locked into a more rigid crystal lattice structure. Additionally, the kinetic energy of the water molecules decreases as they slow down and become more stationary in the solid ice phase.
In terms of the system and surroundings, the system refers to the water molecules undergoing the phase change from liquid to solid, while the surroundings include the environment outside of the water. During the freezing process, the water system loses energy in the form of heat to the surroundings, which can include the air, the container holding the water, or any other nearby objects. This energy loss causes the water molecules to slow down and move closer together, eventually forming a crystalline solid.
Overall, the transformation of liquid water to ice is an exothermic process that involves the release of heat energy from the system to the surroundings, a decrease in potential energy, and a decrease in kinetic energy of the water molecules as they form a more ordered and stationary structure.
