Question

Differeciate between the following on the basis of the parameters mentionedin the bracket:-1)solid and gas (effect of pressure) 2) Liquid and gas (volume) 3)liquid and gas (number of free surface)​

Answer 1

Answer:

Answer

S.No Property Solid Liquid Gases

1. Shape They have a definite shape They do not have a definite shape They do not have a definite shape

2. Volume They have a definite volume They do not have a definite volume They do not have a definite volume

3. Density They have high-density Liquids have less density than solids Gases have the least density

4. The kinetic energy of particles Least More than solids Maximum

5. Compressibility Negligible Low High

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: Matter can flow.

Filled 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 2

Answer:

The physical properties of a substance depends upon its physical state. Water vapor, liquid water and ice all have the same chemical properties, but their physical properties are considerably different. In general covalent bonds determine: molecular shape, bond energies, chemical properties, while intermolecular forces (non-covalent bonds) influence the physical properties of liquids and solids. The kinetic molecular theory of gases gives a reasonably accurate description of the behavior of gases. A similar model can be applied to liquids, but it must take into account the nonzero volumes of particles and the presence of strong intermolecular attractive forces.
