Pressure and Enthalpy

Postby Shannon Asay 1C » Fri Jan 24, 2020 2:27 pm

How does the pressure of the surrounding environment affect the enthalpy of the system?

Pressure and enthalpy are directly proportional so as pressure increases so does enthalpy, and vice versa.

when pressure increases, enthalpy increases; and when pressure decreases, enthalpy decreases

When you are calculating enthalpy, I'm pretty sure the pressure has to be constant. Otherwise the changes in pressure would change the enthalpies as well.

Pressure and enthalpy have a directly proportional relationship with each other, so if one changes, the other will change in response.

Pressure has a direct relationship with enthalpy which is why it is usually easier to calculate enthalpies at STP, using 1 atm as standard.
