### constant pressure

When can we assume constant pressure?

If you are given enthalpy (H), then you can assume constant pressure, since q=deltaH under constant pressure

Hi Bella!

Usually the book or test will tell you are using a constant pressure. Unless they give another pressure, I think it's safe to assume that the pressure is constant.
