Explanation:
Assuming this is an ideal gas:
#W_"env"=-int_(v_i)^(v_f)" P dV"#
#=>W_"env"=-PDeltaV=P(V_"f"-V_"i")#
Let's convert liters to cubic meters first so that our units work out.
#=>V_"i"=0.212" m"^3#
#=>V_"f"=0.08" m"^3#
We also know that
#=>=-(1327358 " N"//"m"^2*-0.132" m"^3)#
#=>~~1.75xx10^5" Nm"#
#=>~~color(blue)(1.75xx10^5" J")#
