the formula used Work=± p(external pressure)multiplied by change in volume

I want to ask should temperature be constant to apply this formula?I mean is this formula applicable only in isothermal condition?

You can use this formula for work anytime( as far as i know). Other equations can be derived from this depending on whether its isothermal/adiabatic. You got to play around with the basic equation to match the data you have.

Be careful when you come across processes with varying pressure.
