An all-season tire, with an internal volume of 18L, is filled to the recommended gauge pressure of 200kPa on a summer day at 20C. The atmospheric pressure is 100kPa. (a) Winter arrives and the temperature has dropped to 20C. Assuming that the tire has no leak, and its internal volume remains unchanged, what is the tire's gauge pressure (in kPa) ? Assume Patm is still 100kPa. Note that we have not yet specified the type of gas in the tire. You should solve theproblem with only the information given thus far. (b) You are now told that the tire is filled with nitrogen. At 20C, how much extra nitrogen (in g) would you have to pump into the tire to bring its pressure back to therecommended level?
