Energy with inflation of Balloon problem

[denverhockeyfan]

Homework Statement

A balloon is being inflated to its full extent by heating the air inside it. In the final stages of this process, the volume of the balloon changes from 4.00 x 106 L to 4.50 x 106 L by the addition of 1.3 x 108 J of energy as heat. Assuming that the balloon expands against a constant pressure of 1.0 atm, calculate delta E for the process.

Homework Equations

delta E = Efinal - Einitial
delta E = q + w
w = F x d

Pressure (P), Volume (V), Internal energy (E) and Enthalpy (H)
delta E = delta H +(- PdeltaV)

delta E = delta H +(- PdeltaV)

You need to display your work ... remember W = - P(deltaV).
