Which best describes why a liquid needs a container when a solid does not?

liquid is fluid in motion, needing to be contained. while a solid state of matter is as such and won't run down the cabinet

When an element or substance is in a liquid state, the particles are joined by less attractive forces than in solids, for this reason the particles of a liquid can move freely.For this reason the particles of a liquid can move freely and need a recipient that contains them .

Liquids have a defined volume but with a variable shape, this means that liquids adopt the shape of the container but always occupy the same space

For example, if we have 4 L of water in a round container, its shape is round and now we put the water in a square container, its shape is now square but its volume is still 4 L (it continues to occupy the same space)

the ratio of the conjugate base to the acid required to attain the desired ph.
