Common Errors in HW 3


- not using proper units was a very common mistake
- not using the right equations for cp(T) and using constant cp
- not doing a "sanity check" on answers, many people calculated the speed of sound ~20 m/s, which is obviously wrong considering the speed of sound at STP is 344 m/s, and the calculations are at a higher temperature
