Answer:

The work done by the gas is 117,300 Joules.

Explanation:

Pressure applied on the gas , P= 102.0 kPa = 102000 Pa ( 1kPa = 1000 Pa

Change in volume of the gas ,ΔV= [tex]1.15 m^3[/tex]

Here the work is done by system so, the value of work done will be negative.

[tex]W=-P\Delta V[/tex]

[tex]=W=-102000 Pa\times 1.15 m^3=117,300 J[/tex]

The work done by the gas is 117,300 Joules.
