Is work greater in adiabatic or isothermal process?

A piston with oxygen has a final volume 1/4 the initial. The temperature is also 5 times greater. Determine pressure change, heat released or absorbed, and work done on or by gas.

2. Relevant equations

the work for adiabatic and isothermal. General w= -integral pdv, conservation of energy deltaV=Q+w

3. The attempt at a solution

I have derived the the expressions for work in both adiabatic and isotherm process from their integrals. ie:- Kln(vf/vi) and -k(vf^{1-gamma}-vi^{1-gamma})/(1-gamma). But I'm not sure how to show that work in isothermal > adiabatic.

For the second part I'm just not sure how to take into account both temperature and pressure, and I can't assume that it's adiabatic/isothermal in the beginning. Any ideas?

Note: I did trying doing the double integral, dvdt....but i still only get an expression only.
