Isobaric

[Tamera Scott 1G]

I understand that isobaric means that pressure is constant and ΔP=0, but what equation does it play a role in?

[Andrea Zheng 1H]

For a constant pressure system, you would be able to use the equation W=-P*deltaV, as the P would be constant and thus can be multiplied by the change in volume to get the work done.

[Annalyn Diaz 1J]

Also in relation to the change in internal energy, heat under constant pressure is dH, which could help with the manipulation of dU=q+w.

[Tarika Gujral 1K]

That also means that you must use the Cv value for ideal gases

MONOATOMIC: 3/2*R
LINEAR: 5/2*R
NONLINEAR: 7/2*R

[LaurenJuul_1B]

it means that you can use the equation w=-PdeltaV

[904914909]

isobaric means that the volume is still changing so you can still calculate work

[Jasmine Chow 1F]

for a isobaric equation to find work you will want to use W= -p delta V.

[Niveda_B_3I]

Isobaric basically means there is no change in pressure, which means you can have work and heat changing your internal energy.

[Cody Do 2F]

Isobaric means there's no change in pressure. As pressure is constant, use the formula w=-p*deltaV to find the work. Other words include Isochoric, which means there's no change in volume (AKA no work) and isothermic, which means no change in temperature (Delta U = 0).

[Vicky Lu 1L]

If there is no change in pressure, as stated as ΔP=0, then there is value for the pressure to be plugged in the equation of w =-PΔV. If the value of pressure or the change in volume are not given, then you can use -Δn*R*T to find work. At a constant pressure,qp equal to ΔH. You can also find q with q=nCpΔT.

[Mhun-Jeong Isaac Lee 1B]

To further complement the above responses, know that W = -PdeltaV is used to calculate work done by expansion against constant P. So since isobaric means constant pressure, this equation would be used.

[LeannaPhan14BDis1D]

What would work most would be w= -pdeltav

[Susanna Givan 2B]

What does isobaric mean for trying to figure out thermodynamics problems?
