Answer:
Hi,hope this helps you...
rigidity, compressibility, fluidity, filling a gas container, shape, kinetic energy and density.
Property
Solid
Liquid
Gases
1.
Shape
They Have definite shape - solid
They do not have definite shape - liquid
They do not have definite shape - gas
2.
Volume
They have definite volume - solid
They do not have definite volume - liquid
They do not have definite volume - gas
3.
Density
They have high density. - solid
Liquids have less density than solids. - liquid
Liquids have least density. - gas
4.
Kinetic energy of particles.
Least - solid
More than solids - liquid
Maximum - gas
5.
Compressibility
Negligible - solid
Low - liquid
High - gas
Rigidity: It is the property of matter to resist the change of its shape.
Compressibility: It is the property of matter in which its volume is decreased by applying force.
Fluidity: It is the ability of matter to flow.
Filling a gas container: On filling a gas takes the shape of the container.
Shape: Having definite boundaries.
Kinetic energy: It is the energy possessed by the particles of matter due to its motion.
Density: It is the ratio of mass with per unit volume
Answer:
for the first one is pic attachment
second one it is
rigidity-it is a quality found in people & objects that don't bend,though they might eventually break.
compressibility -the capacity of something to be flattened or reduced in size by pressure.
Fluidity is the property of any substance which flows.
filling a gas container-Liquids do not fill a gas container completely, while gases fill the gas container completely in which it is kept. This is because the particles of gas can move in all the directions. A container can be filled with gas, provided an external pressure is applied. and the gas particles remain compressed to a small volume.
General Chemistry/Molecular Shape. ... Within this model, the AXE method is used in determining molecular geometry by counting the numbers of electrons and bonds related to the center atom(s) of the molecule. Wikipedia has related information at VSEPR. The VSEPR model is by no means a perfect model of molecular shape!
The energy which is formed due to the motion of the body is known as Kinetic energy
Density is a measurement that compares the amount of matter an object has to its volume .
An object with much matter in an certain volume has high density. It is found by dividing the mass of an object by its volume .
as you can see I put a lot of effort in explaining this question to you so don't forget to mark my answer the brainliest If this helps you
