A bicycle tire is pumped up with air. The air starts out at atmospheric pressure, and a temperature of 285 K. It is compressed into the tire so that inside the tire, the same amount of air occupies 21% of the volume it occupies outside the tire. The air inside the tire heats up tp 298 K during the process.

A) what is the pressure of the air inside the tire?

B) assume the air is entirely nitrogen (N2), and a nitrogen atom has an atomic mass of 14, and 8.5 g of air is pumped into the tire. How many moles of air are pumped into the tire?

Air is pumped into a bicycle tire. The 41 moles of air initially in the tire have a gauge pressure of 1 atm. How many moles of air must be pumped into the tire in order to raise the gauge pressure to 5 atm? Assume that the volume and temperature of the air inside the tire are approximately constant. Ive tried both 205 moles and 164 moles and both come up as incorrect. Not sure why.

An automobile tire is inflated with air originally at 10.0°C and normal atmospheric pressure. During the process, the air is compressed to 29.0% of its original volume and the temperature is increased to 47.0°C. (a) What is the tire pressure in pascals? 395077.4 Pa (b) After the car is driven at high speed, the tire's air temperature rises to 85.0°C and the tire's interior volume increases by 3.00%. What is the new tire pressure (absolute) in pascals?    Use the...

Air (a diatomic ideal gas) at 26.5°C and atmospheric pressure is drawn into a bicycle pump (see figure below) that has a cylinder with an inner diameter of 2.50 cm and length 47.0 cm. The downstroke adiabatically compresses the air, which reaches a gauge pressure of 8.00 105 Pa before entering the tire. We wish to investigate the temperature increase of the pump. The pump is made of steel that is 1.80 mm thick. Assume 4.00 cm of the cylinder's...
