Charles law states that for a fixed mass of gas at constant pressure the volume of the gas is directly proportional to the temperature in Kelvin scale
v1/T1 = v2/T2
Where v1 is volume and T1 is temperature at the first instance
v2 is volume and T2 is temperature at the second instance
Substituting the values in the equation
0.5 L / 203 K = v2 / 273 K
v2 = 0.672 L
The volume of Air after heating is 0.672 L
The goal of an element is to obtain a noble gas configuration (obtaining a full valence shell). Therefore, certain elements will either gain or lose electrons in order to obtain this full valence shell. In the case of sodium chloride, it is easy for sodium (having one valence electron) to give up its one electron. Chlorine (having seven valence electrons) wants sodium’s electron because it completes its outer shell and chlorine obtains this noble gas configuration. Ionic bonds always involve a transfer of electrons.
