3.4 Properties of Water Practice

Properties of Water Matching ice floats water expands when it freezes neutral pH water is not an acid or a base universal solvent water dissolves more solids than any other liquid adhesion water sticks to different molecules cohesion water sticks to itself to form drops Why does water have so many special properties? it is found all over Earth part of each molecule is + and part is - water has no color water is necessary for life Label the Water Molecule Label the image below using the word bank (copy and paste is best - you MUST spell the words correctly). You WILL NOT use all of the terms.Word Bank:covalent bondhydrogenintermolecular forceoxygen oxygen hydrogen covalent bond What is the pH of water? 2 5 7 8 Important Temperatures for Water water melts 0 degrees Celsius water boils 100 degrees Celsius Why does ice float? water EXPANDS when frozen, so it is MORE dense water EXPANDS when frozen, so it is LESS dense water CONTRACTS when frozen, so it is MORE dense water CONTRACTS when frozen, so it is LESS dense Adhesion vs. Cohesion Match the example to the term based on the picture below. Adhesion water sticking to the glass window Cohesion water sticking to itself to form drops What is the chemical formula for water? H2O 2HO H2O2 OH2
