Solid -it has a fixed volume and fixed shape as it has the most force of attraction.
liquid- it has a fixed volume but no fixed shape because  it has less force of attraction and it takes shape of the container in which it is placed.
gaseous-it has neither fixed volume nor fixed shape coz it has the least force of attraction and it can move freely in all directions
