Ok science question here!?

Question

ok i was away on a trip and missed a lot of work, and im trying to get through it but im stuck on a question, here it is

2. What do the particles in ice and boiling water have in common? how are they different?

if you guys could help, please, if i dont get in all the awsners i get a 0!

Answer 1

The particles in ice and boiling water are the same because they are H2O, they are covalent polar compound molecules

They are both moving, but the ice particles are just vibrating in place and the boiling particles are racing around ready to escape as a gas. The ones in ice are close together, touching each other,  the boiling ones are spreading apart.

Density of ice is still less than boiling water, and they will float till they melt.

As a solid they keep their own shape and volume

As a liquid they do not keep their shape, but take the shape of the container, they do keep their volume

As a gas they will not keep their shape or volume

Answer 2

In ice the water molecules are more compact and I think they H-bond with each other to form a crystaline structure.  In boiling water the molecules have no set structure, are farther apart, and are moving around much faster in the solution (untill they eventually break free i.e. steam)
