A potato gun beautifully illustrates Law. As you decrease the volume of the air in between two pieces of potato, the
pressure exerted by the gas increases. This increase in pressure eventually forces the potato out of a tube.

The law that illustrates this is Boyle's Law

Explanation:

Boyle's law: This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Mathematically,

        (at constant temperature and number of moles)

Charles' law: This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Mathematically,

        (at constant pressure and number of moles)

Avogadro's law: This law states that volume of the gas is directly proportional to the number of moles of the gas at constant pressure and temperature.

Mathematically,

        (at constant pressure and temperature)

So, when the volume of the air in the gun decreases, the pressure is increased. The inverse relationship between the volume and pressure of the gas is very well illustrated by Boyle's Law.

Hence, the law that illustrates this is Boyle's Law

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

explanation

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
