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

The new pressure is 21.19 atm.

Step-by-step 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=(P_1V_1)/(V_2)\\\\P_2=(11.1* 21)/(11)\\\\P_2=21.19\ atm`

So, the new pressure is 21.19 atm.
