### Heat Transfer with no temperature given

I'm doing a practice problem that is asking me to find the change in heat without giving me temperatures, and only the moles, the volume, and the pressure. Does anyone know how I go about solving this?

Since it gives pressure, I am assuming that it involves gas. That simply means you would need to use the PV=nrt formula to figure out temperature, solving for T.

I don't know what the question is exactly?
But maybe if the question also suggests/says the change in internal energy is 0, you could use q=-w
and just substitute the given values into w=-PdeltaV ?
Just a thought
