Think about a balloon. if you blow too much air into it and give it too much pressure, the balloon will pop. it’s kind of like that.
Answer : Option D) The particles move enough that they are not fixed in place, and the liquid can flow.
Explanation : The kinetic energy of the particles are allowed to move freely and are in motion when in the liquid state whereas the intermolecular particles can just flow; as the intermolecular attractions between the particles allows the liquid to flow by giving them a force to flow.
When Water freezes or begin to freeze, it molecules start to slow down enough that their attraction arrange into one shape till they melt again.
This is a redox reaction.
Cu²⁺ + 2e⁻ = Cu⁰ copper is the oxidizing agent
Fe⁰ - 2e⁻ = Fe²⁺ iron is the reducing agent
