Calculate Heat Transferred in Gas with Constant Temp & Compression

[jimmy42]

What is the formula to find the amount of heat transferred from a gas when the temperature is constant and the gas is being compressed?

I can't use W=-P deltaV as P will change with V.

So how to do this?

Thanks.

What equations can you use for isothermal expansion?
