6.1 Endothermic and Exothermic Processes
A student places a sample of liquid water, \(\text{H}_2\text{O}(l)\), at \(0^\circ\text{C}\) into an environment maintained at \(-5^\circ\text{C}\). Over time, the sample freezes completely to form ice, \(\text{H}_2\text{O}(s)\), at \(0^\circ\text{C}\). Which of the following statements correctly classifies the freezing process and provides the valid particulate-level justification?
