On the basis of Charle's law, the volume of a given gas mass changes straightforwardly with the absolute temperature of the gas when the pressure is maintained the same. The absolute temperature is determined with the Kelvin scale. There is a need to use the Kelvin scale as zero on the Kelvin scale relates to a complete stoppage of molecular movement.
In the gas law problems, the Kelvin scale is used as the volume and pressure of a gas relies upon the motion or kinetic energy of the particles. The Kelvin scale is equivalent to the kinetic energy of the particles, that is, 0 Kelvin signifies 0 kinetic energy, and on the other hand, 0 degree Celsius is basically the freezing point of water.
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
Filtration is useful for separating sediments that are carried in water for easy drinking without the risk of disease - an example of this is a water purifier
