P V = n R T
P/T = n R/V
so in this problem P/T is constant
12 + 273 = 285 degrees Kelvin
276/285 = 303/T
so
T =303 *(285/276) in degrees Kelvin
subtract 273 to get degrees centigrade
At the start of a road trip, the pressure of the air in a car tyre is 276kPa and the temperature is 12.0 degrees celsius. After driving for some time the pressure in the tyre is now 303kPa.
Assuming that the volume of the air inside the tire remains constant, determine the new temperature?
(assume an ideal gas law)
