Difference between: Solids, liquids, and gases
Answers
Answer:
hello
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. The following figure illustrates the microscopic differences.
Note that:
Particles in a:
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.
Particles in a:
gas vibrate and move freely at high speeds.
liquid vibrate, move about, and slide past each other.
solid vibrate (jiggle) but generally do not move from place to place.
Liquids and solids are often referred to as condensed phases because the particles are very close together.
The following table summarizes properties of gases, liquids, and solids and identifies the microscopic behavior responsible for each property.
Answer:
Properties of liquids:
(i) Liquids do not have definite shape and distinct boundaries.
(ii) Liquids have fixed volume.
(iii) They can be compressed.
(iv) They take up the shape of the container (they can change its shape).
(v) They are fluid and thus can flow like water.
(vi) Their intermolecular force of attraction is less than solids.
(vii)The kinetic energy of its particles is more than solids.
Properties of gases:
(i) Gases neither have definite shape nor have fixed volume.
(ii) They can be compressed much.
(iii) They can take any shape.
(iv) They are neither rigid nor fluids.
(v) Their intermolecular force of attraction is least.
(vi) The kinetic energy of its particles is maximum.
Properties of solids:
(i) Solids have definite shape and distinct boundaries.
(ii) Solids have fixed volume.
(iii) They have negligible compressibility.
(iv) They are rigid (their shape cannot be changed).
(v) Their intermolecular force of attraction is maximum.
(vi) The kinetic energy of its particles is minimum.
