Question

Hi i really need help ASAP

Neon in a piston is compressed to a volume of 11 L. Its original volume was 21 L at 11.1 atm. Find the new pressure in atm. Describe what is happening to the gas.

Answer 1

Answer:

The new pressure is 21.19 atm.

Explanation:

Original volume of the gas was 21 L at 11.1 atm

Neon in a piston is compressed to a volume of 11 L.

It is required to find the new pressure in atm. Boyle's law gives the relationship between volume and pressure. Its mathematical form is given by :

$P_1V_1=P_2V_2$

We have,

$P_1=11.1\ atm\\\\V_1=21\ L\\\\V_2=11\ L\\\\P_2=?$

Using above equation,

$P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{11.1\times 21}{11}\\\\P_2=21.19\ atm$

So, the new pressure is 21.19 atm.
