Homework 8.15

[Kyra Dingle 1B]

Why is part c, q<0, always false in adiabatic processes, in which no energy is transferred as heat? Is this because in these processes, q is simply 0 and would not be negative for the situation? What is an example of a situation in which q would be negative?

[Andy Nguyen 1A]

Since it is an adiabatic process, no heat is transferred, so q must be 0 always. q would be negative if heat was allowed to transfer from the system to the surroundings, making the reaction exothermic.

[Amy Zheng 2l]

No heat is transferred, thus q can't be anything else but zero

[Yeyang Zu 2J]

when the system lost heat to its surrounding, q is negative
