A man drove his car through the Nevada desert one day when the temperature was over 100^circ F. When he started the trip, the gas station attendant found the tire to be 32lb/in^2 When he filled up with gas after crossing the desert, an attendant found the tire pressure to be 38lb/in^2 What is the best explanation for the increase in tire pressure? The temperature in the tire increased, causing an increased tire pressure. The measurements of the pressure were inaccurate. The added weight of the gas caused the extra pressure in the tires. The road wear on the tire caused a decrease in volume and therefore, an increase in tire pressure. The hot temperature caused the springs to expand,which allowed more weight to ride on the tires, thus causing more pressure inside.

Answer 1

The best explanation for the increase in tire pressure is:**The temperature in the tire increased, causing an increased tire pressure.**This explanation aligns with the ideal gas law, which states that for a given amount of gas at constant volume, the pressure of the gas is directly proportional to its temperature (measured in Kelvin). As the temperature inside the tire increases due to the hot desert conditions, the air molecules move more rapidly, increasing the pressure within the tire.
