🧪 M.C.Q.: Choose the correct answer(s) ✅

• 1. Liquid water, solid water, and water vapour contain:
• identical molecules 💧 only water molecules with the formula H₂O different molecules

• 2. Water molecules are moving:
• in solid water and liquid water in water vapour and solid water in water vapour and liquid water

• 3. Water molecules are in contact:
• in solid water and liquid water in water vapour and solid water in water vapour and liquid water

• 4. The speed of water molecules is:
• “high” in the vapour state 🚀 zero in the solid state zero in the liquid state

• 5. In water vapour, between water molecules, there is:
• air vacuum (absence of molecules) dioxygen and dinitrogen molecules

• 6. Solid water is incompressible because:
• water molecules are not compressible molecules are touching and cannot be packed more tightly
