Concept explainers
(a)
Interpretation:
The reason for the more compressibility of gases as compared to liquids is to be determined.
Concept introduction:
The phase is defined as the physical state of a substance. The properties of a phase are determined by the interaction of the potential energy (Ep) and kinetic energy (Ek) of particles. There are three major phases as follows:
1)
2) Liquid
3) Gas
In gases, the value of kinetic energy (Ek) is greater than potential energy (Ep) so the particles can move freely without any force of attraction towards each other while in the case of solids, the value of Ep is greater than Ek so the solid particle can not move freely and remain vibrating at one place. In the case of liquids, the potential energy (Ep) is greater as compared to gases but still, the particles can move but less than the gases.
(b)
Interpretation:
The reason for the greater ability to flow in liquids as compared to solids is to be determined.
Concept introduction:
The phase is defined as the physical state of a substance. The properties of a phase are determined by the interaction of the potential energy (Ep) and kinetic energy (Ek) of particles. There are three major phases as follows:
1) Solid
2) Liquid
3) Gas
Potential energy (Ep) tries to keep the molecules together and act as the intermolecular forces while kinetic energy (Ek) is associated with the motion and tries to move apart the molecules.
In gases, the value of kinetic energy (Ek) is greater than potential energy (Ep) so the particles can move freely without any force of attraction towards each other while in the case of solids, the value of Ep is greater than Ek so the solid particle can not move freely and remain vibrating at one place. In the case of liquids, the potential energy (Ep) is greater as compared to gases but still, the particles can move but less than the gases.
