Suppose you start your day in Denver, on a cool 10∘C spring day. The local atmospheric pressure is 85 kPa. You fill your car's tires until the gauge shows 210 kPa (about 30 psi). You then drive up to Fairplay, Colorado, where the atmospheric pressure is lower-- 70 kPa --and the temperature drops to 0∘C. When you finish lunch, you check your tire pressure. A. What does the gauge read? and Units. Please show the math on how to solve...

On a cold rainy day where it was -12°C, a nitrogen-filled bike tire placed outdoors has the pressure of 5.44 atm. The tire volume was 6.7 L.You then take the bike indoors where the temperature was 25 °C. Assuming the volume of the bike tire does not change and no leaking occurred, answer the following two questions: 1. What is the pressure of the bike tire now? 2. How many moles of nitrogen gas does the tire contain?

At sea level, water boils at 100 °C, and the absolute atmospheric pressure is 101 kPa. As the atmospheric pressure above water decreases, the temperature required for boiling also decreases, at a rate of 3.1 kPa per "C. For the system shown below: a. What is the absolute atmospheric pressure at an elevation of 4100 m, assuming a constant unit weight of air of 11.80 N/m3? b. What will be the boiling temperature for water at this elevation? Elev. =...

Your tire pressure gauge indicates that the pressure in your cold tires is 250 kPa on a mountain at an elevation of 3500 m. (a) What is the absolute pressure in your tires? (b) After your drive down to sea level, your tires have warmed to 25 C. What does your tire pressure gauge indicate now? assume standard atmospheric conditions

Q2)
2) An automobile tire is filled to a gauge pressure of 196 kPa
when its temperature is 20°C. (Gauge pressure is the difference
between the actual pressure and atmospheric pressure.) After the
car has been driven at high speeds, the tire temperature increases
to 51°C.
(a) Assuming that the volume of the tire does not change, and
that air behaves as an ideal gas, find the gauge pressure of the
air in the tire.
(b) Calculate the gauge...

An automobile tire is filled with air at a pressure of 44 lb/in2 at 20 °C. The temperature drops to -5 °C. What is the new tire pressure in lb/in2, assuming the volume of the tire does not change? Some students calculate a pressure of 0-is this correct? If not, what mistakes might they have made to obtain a pressure of 0 in their calculation? 1.

when the temperature of an automobile tire is 20 degrees c, the pressure in the tire reads 29 psi on a tire gauge. (the gauge measures the difference between the pressures inside and outside the tire.) what is rhe pressure when the tire heats up to 39 degrees c while driving? you may assume that the volume of the tire remains the same and that the atomspheric pressure is a steady 14 psi.

5. If you put air in your tires in La Paz, Bolivia, and your pressure gauge is reading 25 psig, what is the absolute pressure inside the tire, in psia? (The standard atmospheric pressure in La Paz is about 62 kPa!) Answer: between 30 and 35 psia. 2. A manometer like the one we drew in class has water in the column. The side that is open to standard atmospheric pressure is 20 cm lower than the side open to...
