Describe how molecular motion and distance between molecules change as ice is heated to become a liquid and then a gas

Described in the explanation section

Explanation:

Ice is the solid phase of water and this phase, the water molecules usually have very little energy and therefore can't detach from each other. This is because the water molecules are closely packed together in a regular arrangement normally called lattice.

Now, when the ice is heated to become a liquid, the energy of the water molecules increases and thus some of them will have enough energy to overcome the intermolecular forces that had been keeping them closely packed in the ice phase. This will then make the water molecules to move further apart thereby forming liquid water.

Now, when the molecules are heated further, the liquid water will now turn into water vapor, which is the gas phase of water. The molecules in this gas phase will have more energy than in the liquid phase because the average distances between each of them will be much larger than the size of the molecules themselves.

i'm pretty sure its b i might be wrong though!

let that person have a turn to speak : )
