Given:
P = 8.25 atm
V = 2.52 L
n = 0.550 mol
use:
P * V = n*R*T
8.25 atm * 2.52 L = 0.55 mol* 0.08206 atm.L/mol.K * T
T = 461 K
= (461 - 273) oC
= 188 oC
Answer: 188 oC

Suppose you have filled a 35.0 L car tire with air at a pressure of 40.0 lb / in2. If you attach a balloon to the tire and let the air out of the tire into the balloon until the pressure is 14.7 lb / in2, what is the final volume to which the balloon will expand, assuming that the temperature is constant and that the volume of the tire remains constant. (Hint: first calculate the final volume of the...
