Example 4

medium
A gas occupies 2.402.40 L at 1.001.00 atm. If the pressure increases to 1.501.50 atm at constant temperature, what is the new volume?

Solution

  1. 1
    Use Boyle's law: P1V1=P2V2P_1V_1 = P_2V_2.
  2. 2
    V2=P1V1P2=1.00×2.401.50=1.60 LV_2 = \frac{P_1V_1}{P_2} = \frac{1.00 \times 2.40}{1.50} = 1.60\,\text{L}.

Answer

1.60 L1.60\,\text{L}
At constant temperature, pressure and volume vary inversely for a fixed amount of gas. Increasing the pressure lowers the volume by the same factor.
