On the basis of physical properties matter is classified into solid, liquid and gases. In solid particle are
arranged very close to each other They are held together by strong forces of attraction Because of
these strong forces particles in solid can only vibrate about their position They cannot move from one
place to another like liquid's an gases
a) What is the effect of the given arrangement of position in solid or the shape and
volume?
b) Can can solid be compressed what will happen when an access forces supplied on solids?
c) What happened put the particles in a solid when it is heated when does a solid melt?
d) Compare the arrangement of particles in solids with that in liquid's
Answers
Answer:
Explanation:
a) In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.
b) There are very small spaces between the particles in a solid. Particles are held together by forces of attraction. For example, the particles in solids are closely packed and have strong forces between them explains why solids have a fixed shape and you cannot compress them.
c) When a solid is heated the particles gain energy and start to vibrate faster and faster. Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.
hope it helps u !!
