reversible expansion

[Mallika Singh 1G]

I know the formula with the integral is for the reversible expansion, but does anyone know what the area under the curve means?

[Jiyoon_Hwang_2I]

The area under the curve usually represent work

[Sydney Pell 2E]

The area under the reversible expansion curve is the work done during the expansion. You can solve for this using the integral formula for reversible expansion, as the definition of an integral is the area underneath the curve.

[Hannah Pham]

It represents work done by expansion

[Veronica Lu 2H]

the area under the curve is the work by expansion
