Trying to work out isothermal heat transfer

[abbie230391]

Homework Statement

A gas mass 0.115kg undergoes an increase in volume from 0.25m cubed to 0.56m cubed. initial temp 32 degrees c and initial pressure 1.2bar. work out heat transfer??

Homework Equations

W=P1V1 ln(V2/V1)
W=mRT ln(V2/V1)
P1V1/T1=P2V2/T2
Q=U2-U1+W
PV=mRT
