It is important to check tire pressure periodically, especially when the outside temperature drops. You can see why this is so by calculating the tire volume after a large drop in temperature as follows: A well-inflated tire holds about 11 L of air at 298 K (25$\degree$C). If the temperature drops to 273 K (0$\degree$C), what is the new volume of the air in the tire?
A) It is not possible to determine because the temperature has dropped to 0$\degree$C.
B) 0 L
C) 10. L
D) 12 L
E) 7300 L

According to Charles's law, the volume of a gas is directly proportional to its temperature, assuming constant pressure. So, if the temperature drops from 298 K to 273 K, the volume of the air in the tire will also decrease proportionally. Using the formula V1/T1 = V2/T2, where V1 is the original volume (11 L), T1 is the original temperature (298 K), T2 is the new temperature (273 K), and V2 is the new volume (unknown), we can calculate:
11 L / 298 K = V2 / 273 K
V2 = (11 L * 273 K) / 298 K = 10.03 L
Therefore, the new volume of air in the tire is approximately 10 L.
