What does q with subscript p mean in relation to Constant pressure calorimetry? it seems to mean that if you're in a constant pressure environment, that the calculation of how he flowed, q, is equal to the change in enthalpy. From my reading it also seems to mean that this is only the case and a constant pressure enviriment. if P constant than in a rxn, q = s m change temp = enthalpy of reaction, another term for "heat flow of reaction".
