C Programming (only answers in C please): The National Football League (NFL) is currently investigating whether the Patriots, Colts, or any other entity purposely deflated footballs during this year's AFC Championship game. Not so fast says Professor Bill Belichick of the Foxboro Institute of Technology (FIT). He claims that it is natural for a football starting with a PSI of 12.5 to easily deflate during the game using Guy-Lussac's Laws. Given that it was raining that day, water pressure vapor is another variable to be considered. Your job if you choose to accept it is to use the information in the link(s) below to create a function or set of functions that could be called to support Professor Belichick's position that a ball starting at a PSI of 12.5 could easily deflate to 12.1 given the game time temperature of 51 degrees, and down to 11.7 considering the water pressure vapor in the air caused by the rain. Pass in parameters such as temperate, water and air pressure, and other factors to your functions(s), so that the NFL could model any conditions in the future with their footballs. http://www.sportsgrid.com/nfl/science-is-all-like-ooh-ooh-we-can-explain-deflate-gate-with-our-magic/ Additional details can also be found at: http://www.reddit.com/r/nfl/comments/2sxul5/deflategate_could_the_weather_have_an_effect_on/
