Answer 1

$\begin{array}{cccc}\text{Property}& \text{Solid state}& \text{Liquid state}& \text{Gaseous state}\\ \text{Rigidity}& \text{Highly rigid}& \text{Less rigid as compared to solids}& \text{Not rigid}\\ \text{Compressibility}& \text{Negligible}& \text{Low}& \text{Very high.}\\ \text{Fluidity}& \text{Do not flow}& \text{Flow from a high to}& \text{Flow in all directions}\\ & & \text{level to a low level}& \\ \text{Filling a gas}& \text{Do not need a}& \text{Need a container to hold them.}& \text{Need a container to contain them}\\ \text{container:}& \text{Container to contain them}& \text{Take the shape of the container}& \text{Gasses fill a container}\\ & & \text{in which they are kept.}& \text{Completely.}\\ \text{Shape}& \text{Definite shape}& \text{No definite shape.}& \text{Gases do not have}\\ & & \text{Liquids attain the shape of the}& \text{a definite shape}\\ & & \text{vessel in which they are kept}& \\ \text{Kinetic energy:}& \text{Least kinetic energy}& \text{More kinetic energy}& \text{Maximum}\\ & & \text{than solids but less}& \text{Kinetic energy}\\ & & \text{than that of gases}& \\ \text{Density:}& \text{Highest density}& \text{Liquids have a lower density}& \text{Lowest density}\\ & & \text{thansolids but higher than that of liquids}& \end{array}$
