independent Activity 3: I KNEW IT!Material at Room Temperature:Example Material: WaterState: LiquidHeat is Applied:What Happens When Heated:When heat is applied to water, the temperature of the water increases. As the temperature rises, the molecules in the water gain kinetic energy and move faster. This process continues until the water reaches its boiling point (100°C at standard atmospheric pressure). At this point, the water begins to undergo a phase change from liquid to gas (steam). The molecules break free from the liquid state and enter the gaseous state, resulting in vaporization.Draw a Picture of What Happens When It Is Heated:[Illustration of water being heated with steam rising]Heat is Removed:What Happens When Cooled:When heat is removed from water, it loses kinetic energy. As the temperature decreases, the movement of the molecules slows down. If enough heat is removed, the water will eventually reach its freezing point (0°C at standard atmospheric pressure). At this stage, it undergoes another phase change from liquid to solid (ice). The molecules arrange themselves into a structured lattice formation characteristic of solid ice.Draw a Picture of What Happens When It Is Cooled:[Illustration of water freezing into ice]In summary:Heating causes water to transition from liquid to gas.Cooling causes water to transition from liquid to solid.Answer: Water transitions between states when heated or cooled; heating turns it into steam while cooling turns it into ice.
