… and we are back. Last week I had an exam in Thermodynamics. One of the problems asked if the problem could occur adiabatically. I answered because the vessel is made in the USA and therefore very well insulated so heat transfer would not occur. To explain why this is funny, every time we had a problem in class involving no heat transfer the professor would say it was because the system was made in the US. I got the problem wrong because I didn’t explain about in fact it was because I didn’t say or some other stuff which you are probably not interested in (the fact that the TA graded it probably didn’t help.
