1. The heat capacity of water is very high. 2. Water must be at a very high heat before evaporation occurs. 3. Water is a solvent. 4. Water molecules facilitate cohesion and adhesion 5. Liquid water is less dense than frozen water.
Work Step by Step
1. Water takes more time to heat and cool than other liquids due to its ability to hold onto heat. This is called its heat capacity. 2. Evaporation can only occur when water is hot enough for its hydrogen bonds to break. 3. Substances submerged in water break down due to the polarity of water. 4. Hydrogen bonds cause water molecules cling to other water molecules as well as other polar surfaces. Cohesion is when water molecules cling together (example: water drops), and adhesion is when water molecules cling to other polar surfaces (example: water sticking to leaves). 5. The hydrogen bonds within water stretch out and cause water to expand when it freezes. This causes water to become less dense, which is why ice floats.
