An automobile tire is filled to a gauge pressure of 195 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 55°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. kPa (b) Calculate the gauge pressure if...

It is recommended that you inflate the tires on your car when they are at ambient temperature. Suppose you inflate the tires to 35 psi gauge with air at T = 20 °C. The tire heats up when you drive to 37 °C. Additionally, because the tire is spinning, it expands due to centripetal effects and the volume of the tire increases by 3%. What is the gauge pressure in the tire now?

(a) What is the gauge pressure (in atm) in a 25.0°C car tire containing 3.56 mol of gas in a 28.0 L volume? (Enter your answer to at least 2 decimal places.) _____ atm (b) What will its gauge pressure be (in atm) if you add 1.40 L of gas originally at atmospheric pressure and 25.0°C ? Assume the temperature returns to 25.0°C and the volume remains constant. (Enter your answer to at least 2 decimal places.) _____ atm
