Homework Statement
One mole of ideal gas expands isothermally at 20°C against a constant pressure of 1 atm from 20 to 30L. (1 atm = 1.013 x 105Pa; 1 m3 = 1000L
Find q, w, ΔE, and ΔH in Joules
Homework Equations
ΔE = q + w
w = -[itex]\int[/itex]PdV
H = E + PV
The Attempt at a Solution
I solved for work using the second equation listed above. Since pressure is constant, I removed it from the integral and simply integrated the volume from 20L to 30L. This resulted in -10 atm x L.
Converting that to Joules using the conversion factors given, I obtained -1013 J as the thermodynamic work.
But then how do I obtain the thermodynamic heat?
