Under what circumstances can we use the delta U=delta H+ w equation? Like what allows delta H to be interchangeable with q?

[Justin Nguyen 3E]

I think that q and deltaH can be interchangeable when the process involving these values is carried out at constant pressure.

[Chinmayi Mutyala 3H]

deltaH equals q under constant pressure.

[Eliana Witham 2H]

At constant pressure, you can use deltaU = deltaH - P(deltaV) because q=deltaH and w= -P(deltaV).

Must be in constant pressure and a open or closed system.

[Ethan Laureano 3H]

Constant pressure since q_p=deltaH

[Ranen_Chang_2G]

The context where is in constant pressure. In a biological focus, we can use because reactions happen at constant pressure.

This can be used when the process is under constant pressure.

[Kayla Booker 1F]

When the system is at constant pressure, q is equivalent to delta H
