Can you find the mistake?
So i am in a class called thermodynamic (guess what we study) and the professor (even though its his first day at a new university) made two (three) large mistakes that caused me great pain. See if you can find the mistake before i give you the answer.
1. We have a metal box and we make a vacuum on the inside. Now air pressure is pushing on the outside of the box and nothing is pushing from the inside so because of we don't have newton's 3rd law of opposite forces the box collapses in on it self.
2. Now when two bodies are not in thermal equilibrium because of the zeroth law of thermodynamics heat will always flow from the hot body to the cold.
1. This mistake was one people commonly make in high school physics. the two forces are not equal and opposite (there are equal and opposite forces there he just didn't talk about them) they are two different unrelated forces and newton's DOES apply here (it always applies) but it is not the cause of the phenomenon as described. (its the 2nd law of thermodynamics that would be the cause)
2. Come on. the class is called Thermodynamics and you misquote a law!* What is mentioned above is the second law. the Zeroth, is different. It is just a restating of the transitive property (in mathematics). if a=b and b=c then a=c THAT is the zeroth law. t
* not just any law either possibly the single most important law in all of physics, chemistry and science in general.
