Freezing

The video tutorial explains the concept of freezing, a phase change where matter transitions from liquid to solid. It discusses how temperature affects molecular behavior, leading to crystallization and freezing. The tutorial covers freezing points of various substances, such as water and mercury, and provides examples of freezing in nature and food. It also contrasts freezing with melting, another phase change. The video concludes with a reflective question about why ice melts in water.
