A man drove his car through the Nevada desert one day when the temperature was over 100°F. When he started the trip, the gas station attendant found the tire to be 32 lb/in². When he filled up with gas after crossing the desert, an attendant found the tire pressure to be 38 lb/in². The best explanation for the increase in tire pressure is: The road wear on the tire caused a decrease in volume, therefore an increase in tire pressure. The temperature in the tire increased, causing an increased tire pressure. The hot temperature caused the springs to expand, which allowed more weight to ride on

anonymous · Answer

the temp. in the tire increased, causing an increase in tire pressure.

temp is directly proportional to pressure.
hot day, temp. is more so presssure increases on hot day.
