what are the molecule arrangements of a solid? liquid? and gas? what is ta temperature of a liquid?

Think about it.

For a gas the molecules are randomly oriented usually with a great deal of space between them (except at high pressures) and they fill the space in which they are located.
For a liquid the molecules are closer together but they do not fill the space in which they find themselves.
For a solid, the molecules are fixed in an crystalline arrangement.
