- A cup of water was left outside one night, and turned into ice. What is a conclusion that can be made about the temperature?
- Water in its solid form (ice) floats in water in its liquid form. What can you infer about the density properties of water in different phases?
- Explain the process of water freezing. What is occurring structurally?
Answer Key/Rubric
- Melting is the phase transition of a solid to a liquid.
- Freezing is the phase transition of a liquid to a solid.
- Evaporation occurs when a liquid becomes a gas.
- Condensation occurs when a gas becomes a liquid.
- The temperature must have dropped below 32°F/0°C since it is the temperature at which water freezes.
- Density of water is not the same in its different phases. Frozen water is less dense that liquid water, therefore it floats.
- Water is composed of two molecules of hydrogen, and one molecule of hydrogen (H2O) which are connected by strong covalent bonds. Water molecules are also attracted through weaker hydrogen bonds, in which the hydrogen atoms are positively charged and the oxygen atoms are negatively charged. As water-cools towards its freezing point, the hydrogen bonds adjust to keep the oxygen atoms apart, losing energy and forming bonds that stick the atoms together in a lattice formation known as ice.
