## Homework Statement

10 moles of an ideal gas at 100 atm pressure are expanded isothermally against a constant pressure of 10 atm, to 10 at. calculate Q W deltaU and delta H (Take temp to be T)

## Homework Equations

PV = nRT

DeltaH = Q (for constant P)

DeltaU = Q-W

U = H+PV

W = Integral(PdV)

## The Attempt at a Solution

I wish i knew where to start...

Isothermal means a constant pressure, in this case 10 atm. ...i just have no idea.

PV = nRT

V1 = .8314T

V2 = 8.314T

W= Integral(PdV)

W = PIntegral(dv)

W = P(v2-v1)

W = 74.826

Got IT!
