So if a state function doesn't refer to when all of Ohio goes bowling together, then what [Men at a bowling alley]
Well in the context of thermodynamics, a state function refers to any property that depends
only on the current state of a system, and not on the path taken to get to that state.
Sort of like the relief you feel when you finally get back home to New York for Thanksgiving. [Man on a plane and the child seated behind crys]
Your flight may have been delayed three times, but at least you got there in time for the
turkey. [Family having thanksgiving dinner]
So that being said, we can immediately rule out choice B, which says that state functions
are dependent on path.
And, similarly, choice D must be incorrect because we now know that choice A is true.
So let’s check in with choice C.
Is temperature a state function? [Man walking through a desert]
Well, does the temperature of a system depend on the path we take to get to that temperature? [Man walks into a snowy, cold terrain]
As far as we know, zero degrees Celsius is the same temperature regardless of whether
we start at a hotter or colder temperature, even though it might not feel like it. [Man standing in the snow]
Yeah, snow feels a lot colder when you’re coming right out of a Jacuzzi.
Though why you’d be doing that, we don’t know. [Man in a jacuzzi]
Anyway, temperature is a state function, so choice C is incorrect.
Meaning that choice A is the correct answer, regardless of how you came to that conclusion.
Well, except if you cheated. [Man reading a textbook]
Academic dishonesty is so wrong it makes everything wrong.
There's logic in there somewhere.
Don't look too hard for it…
