P: Good conductor of heat and electricity - R: the delocalized electrons are
free to move around the structure

P: High melting and boiling points - R: the bonds in metals are very strong

P: Ductile (can be stretched and squashed) - R: because the electrons are free to move, the atoms can slide over each other.

P: Malleable (can be hammered into shape) - R: the bonds in metal don't break easily

If 9.5 atms of pressure were increased to 25 atms of pressure, what would be the final volume

nordsb [41]

Answer:

The final volume of the gas is 36.1 L.

Explanation:

Given:

Initial pressure of the gas is, $P_1=9.5\ atm$

Final pressure of the gas is, $P_2=25\ atm$

Initial volume of the gas is, $V_1=95\ L$

Final volume of the gas is, $V_2=?$

Here, we shall use Boyle's Law which states that for a process under constant temperature, the pressure of the gas changes inversely with the change in volume.

Here, the pressure is increased. So, the volume of the gas is decreased.

Therefore, as per Boyle's Law:

$P_1V_1=P_2V_2\\9.5\times 95=25V_2\\902.5=25V_2\\V_2=\frac{902.5}{25}\\V_2=36.1\ L$
