Imagine the following design for a simple tire pump The pump is filled with a volume...
In the course of pumping up a bicycle tire, a liter of air at atmospheric pressure is compressed ISOTHERMALLY to a pressure of 7 atm. (Air is mostly diatomic and oxygen). (a) if the temperature is initially 300 K, what is the temperature after compression? (b) what is the final volume of this air after compression? (c) how much work is done in compressing the air?
A bicycle pump inflates a tire whose volume is 515 mL until its internal pressure is 6.30 bar at a temperature of 20.7 oC. a. How many moles of air does the tire contain? b.What volume of air (in L) at 1.01 bar and 20.7 oC did the pump transfer?
An automobile tire is filled to a gauge pressure of 185 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 57°C. Please help with both parts of this problem. Thanks!

1) 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 pressure if...
Please help me solve this problem and show your work 21. A tire is filled with air at a pressure of 5 atm when its temperature is 20° C. After the car has been driven at high speeds, the tire temperature increases to 68.5C.

18. A car tire is filled to 36.0 psi at 75 °F. If the volume of the tire and the amount of air particles remains unchanged, while the temperature drops to 25 °F, what does the pressure in the tire become? A) 12.0 psi B) 39.7 psi C) 27.8 psi D) 36.0 psi E) 32.6 psi
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.
A car tire has a recommended rating of 2.518 atm. While parked, the tire has at the temperature of 11.0°C, inflated to a volume of 10,4 L and with a pressure of 2.109 atm. When driving on a hot day, the tire warms to 62.0.Cand its volume expands to 10.9 L a) Assuming there are the same molecules in the tire (n is constant) Does the pressure in the tire exceed its recommended rating on the hot day? b) Find...
