Sam's bike tire contains 15 units of air particles and has a volume of 160mL. Under these conditions the pressure reads 13 psi. The tire develops a leak. Now it contains 10 units of air particles and has contracted to a volume of 150mL. What would the tire pressure be now?

    Use ideal gas equation, with T constant.

    pV = nRT = > pV / n = RT = constant

    n = K * [units of particles]

    pV / [units of particles] = constant

    13 psi * 160 mL / 15 units = p * 150 mL / 10 units = >

    => p = [13psi*160mL/15units]*[10units/150mL] = 9.2 psi
