There is a PV diagram with ABC and the cycle is moving clockwise.

segment AB is isobaric
BC is isochronic
AC cannot be determined

The delta U for this is zero and the W=positive.

The last questions asks if the heat flow Q is positive, negative, or zero and the answer given is that it is positive.

I do not understand how to determine what Q is. Is it positive because the W is positive?

Thank you for the help!
