Final answer:
The statement that proper air pressure in tires is not important for a safe trip is false - correct tire pressure is crucial for safety, fuel efficiency, and tire longevity. Recommended pressures are found in the manual or on the car, and tires should be checked when cold.
Step-by-step explanation:
Proper air pressure in your tires is extremely important for having a safe trip, therefore the statement is false. Maintaining the correct tire pressure ensures a smoother ride, optimal gas mileage, and minimizes tire wear. The recommended pressure for each model of car is typically listed in the owner's manual or on a sticker inside the door, and this is different from the maximum pressure listed on the tire itself. Tire pressure should be measured when the tires are cold, as driving increases the air temperature inside the tires, which in turn increases the pressure.
Furthermore, safety is also compromised if tire pressure is incorrect, as it affects the vehicle's handling, braking, and the overall stability on the road. Avogadro's Law helps to explain how pressure increases in the tire as air is added. However, once a tire reaches its optimal volume, further pumping can excessively increase pressure, posing the risk of a tire burst under certain circumstances.
