### Delta H and q

How are delta H and q related? Are they the same thing and can be used interchangeably? In what contexts do you use each one?

delta h is the change in enthalpy of the system and q is the heat given off or absorbed in the system

$\Delta$H=q at constant pressure and with no nonexpansion work.
