Problem

A 93-L sample of dry air cools from 145°C to −22°C while the pressure is maintained at 2.85 atm. What is the final volume?

Solution
  • According to Charles' Law, temperature is directly proportional with volume

  • Using this relationship, we can establish an equation to find the final volume of dry air
