Well-known cyclist "Chubs" Miller has a mass of about (8.71x10^1) kg. When Chubs gets off his bicycle, the absolute pressure in each tire decreases by (-2.340x10^3) Pa from its starting pressure of (6.7x10^5). Assuming the volume change of the tire is negligible and the tire wall is thermally insulating, what is the temperature change (from standard ambient temperature) of the gas in the tire after Chubs leaves the seat?

Note: Your answer is assumed to be reduced to the highest power possible.
