Wow, so the Sunday before exams was spent frantically studying for all of my courses. That's when I was suddenly overcoming with an allergy spell, sneezing non-stop for what seemed like long seconds. I decided to take matters into my own hands and dust of my desk and clean all the unnecessary pencil shavings and eraser bits from my desk using the handy dandy DUST OFF! (basically pressurized air in a can). Using this, I sprayed the air to get all of the random pieces of stuff out of my keyboard when suddenly by hand felt a stinging cold coming from the can. WHAT IS THIS MADNESS?! That's when Atmospheric DOC! appeared out of 101,000 Pa pressure. He told me that the ideal gas law could explain such cold wonder. I thought that it was due to the high gusty trade winds reported on channel two news.
However, Atmospheric DOC! said to analyze the can more closely. As I pressed the trigger releasing the pressurized air, the amount of air in the can lowered, as well as the pressure in the can. However, because volume stayed the same, and according to the ideal gas law, the temperature as well decreased. WOW! So it wasn't the trade winds after all. After a quick slap on the head from Atmospheric DOC! he disappeared again. Lesson of the week: Dusting creates Cold Temperatures thereby is can make snow! DOC! if you're reading this....HI!
