All right, guys, we're doing problem number thirty four in Kept in Chapter five. The chemistry of central science. So on there were conditions. Will envelop change of process equal the amount if he transferred into or out of the system? So that's going to be a constant V or rather constant volume or constant pressure, which is represented as P. Now during constant pressure process system releases heats the surroundings. Does the entropy of the system increase or decrease during this process? So remember, at a constant pressure system, Delta H is equal to Q. So since she's being released, Q is less than zero. So that also means that Delta H is going to be less than zero as well. So Delta Ages going to decrease during this during this process? Yeah, so they want to know, like no. For part. See, in a concentration process, Delta H is equal to zero. What conclude about e Q and W? So Delta age is equal to zero. Oh, and since at a constant pressure and Delta H is also equal to Q, Hugh Hugh will be equal to zero. Remember, Delta E is equal to que plus w. That means Delta E will be equal to work at its impression process where Delta
