Isobaric

Postby Lauryn Jordan 1F » Tue Mar 13, 2018 7:42 pm

for an isobaric equation, since delta p = 0, is the internal energy = delta h?

Isobaric means constant P. ΔU=w + q
At constant P, the change in heat is equal to the change in enthalpy by definition.
At constant P, w= -P(ex)ΔV.

So, the ΔU= ΔH -P(ex)ΔV in isobaric conditions.
