The pressure of an automobile tire is measured to be $190 \mathrm{kPa}$ (gage) before a trip and $215 \mathrm{kPa}$ (gage) after the trip at a location where the atmospheric pressure is $95 \mathrm{kPa}$. If the temperature of air in the tire before the trip is $25^{\circ} \mathrm{C},$ the air temperature after the trip is (a) $51.1^{\circ} \mathrm{C}$ (b) $64.2^{\circ} \mathrm{C}$ (c) $27.2^{\circ} \mathrm{C}$ (d) $28.3^{\circ} \mathrm{C}$ (e) $25.0^{\circ} \mathrm{C}$

Step 1
Step 1: Calculate the absolute pressure before the trip by adding the atmospheric pressure to the gauge pressure: $P_{\text{abs, before}} = 190 \, \text{kPa} + 95 \, \text{kPa} = 285 \, \text{kPa}$ Show more…

The pressure of an automobile tire is measured to be 190 kPa (gage) before a trip and 215 kPa (gage) after the trip at a location where the atmospheric pressure is 95 kPa. If the temperature of air in the tire before the trip is 25°C, the air temperature after the trip is (a) 51.1°C (b) 64.2°C (c) 27.2°C (d) 28.3°C (e) 25.0°C

To gauge pressure of an automobile tire is measured Is measure to be 200 kpa before a trip and 220 kpa After the trip at a location where the atmospheric pressure is 90 kpa. Show the volume of the tire remains constant at 0.035 m^3, Determining the pressure increases in the absolute temperature of the air in the tire

An automobile tire has a volume of 0.0150 $\mathrm{m}^{3}$ on a cold day when the temperature of the air in the tire is $5.0^{\circ} \mathrm{C}$ and atmospheric pressure is 1.02 atm. Under these conditions the gauge pressure is measured to be 1.70 atm (about 25 $\mathrm{lb} / \mathrm{in.} .$ ). After the car is driven on the highway for 30 min, the temperature of the air in the tires has risen to $45.0^{\circ} \mathrm{C}$ and the volume has risen to 0.0159 $\mathrm{m}^{3}$ . What then is the gauge pressure?
