Give differences between solids and liquids, liquids and gases on the basis of :rigidity , density, kinetic energy.
Answers
Explanation:
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Answer:
RIGITY:
Solid:
The molecules in solids are closely bound togrther, they can only vibrate on thier mean position. This means solids have a definite shape.
Liquids:
The molecules in liquid are at some distant. It is a only state with definite volume but no fixed shape.
Gases:
The molecules of gases are far apart and are easy to compress. They expand to fill the space.
DENSITY:
Solid:
Solids are usually much more denser than liquids or gases because their molecules are packed together, but not always.Aerogal, a very unusal human-made solid, is about 500 times less dense than water. Many solid material will melt when heated.
Liquids:
The molecules of liquids are also packed relatively together. Consequently, liquids are much denser than gases. The density of liquid is typically about the same as the density of solid state of the substance.
Gases:
Since gases all occupy the same volume on a per mole basis, the density of a particular gas is dependent on its molar mass. A gas with a small molar mass will have a lower density than a gas with a large molar mass.
KINETIC ENERGY:
Solid:
Solid particles have relatively little kinetic energy and vibrate in place.
Liquid:
Liquids have more kinetic energy than solids. If you add heat energy to a liqid, the particles will move faster around each other as their kinetic energy increases.
Gases:
The kinetic energy of the transational motion of an ideal gas depends on its temperature.Gases have the most kinetic energy so ly around the air.
