An automobile tire has a pressure of 325 KPA when the temp. is 10 degrees Celcius. If the temp of the tire rises to 50 degrees celcius and the volume is constant, what is the new pressure???
Science quiz!!?
PV = nRT
T is in Kelvin, so 10 C = 283 K and 50 C is 50 + 273 K.
V,n, and R are constant
so P is proportional to T.
P1 = a T1 ==%26gt; a = P1/T1.
P2 = a T2 = P1/T1*T2
