The answer in the book says W at

**constant temperature**gives a greater value for the given case.

But when I tried to solve it mathematically, I got greater value of W at

**constant pressure**which is plain wrong. I don't understand where did I go wrong.

For

**constant pressure**my result was:

W = p(2V-V) =pV = (nRT/V)*V =nRT

For

**constant temperature**my result was:

W= nRT ln(2V/V) =nRT ln(2) =0.69 nRT

So, I got lesser value for constant temperature than constant pressure.

Where did I went wrong?
