Problem 8P

An automobile tire has a volume of 0.0185 m3. At a temperature of 294 K the absolute pressure in the tire is 212 kPa. How many moles of air must be pumped into the tire to increase its pressure to 252 kPa, given that the temperature and volume of the tire remain constant?

Solution 8 P:

Step 1 of 2:-

Here we have to find the number of moles of air pumped into the tire to increase the pressure to 252 kPa.

We are talking about the absolute pressure here.

The initial volume, temperature and pressure was,
