Answer:
1144J
Explanation:
To find the heat gain by the system you consider that all heat is generated by the work done by the piston, that is:
[tex]Q=W=P\Delta V[/tex]
P: constant pressure = 1.93atm= 1.93(101325pas) = 195557.25J/m^3
ΔV: change in the volume 8.47-2.62L=5.85L
5.85(1000cm^3)=5.85(1000(10^-2m)^3)=5.85*10^{-3}m^3
By replacing the values of V and P you obtain:
[tex]1Q=(195557.25J/m^3)(5.85*10^{-3}m^3)=1144J[/tex]
hence, the gain by the system is 1144J
