State Property

Is heat a state property always or only when its at constant conditions? Why?

Thanks :)

Heat isn't a state function because different paths can result in different amounts of heat that's transferred. For example, if you think of the different ways that a person can reach the mountain top, you can see that the paths require differing amounts of energy. Similarly, in 2 different reactions that result in the same product, the paths may be different. Because the paths are different, the amount of heat released or absorbed may be different.
