The initial pressure and volume of a gas enclosed in a cylinder are respectively 1 × 105 N/m2 and 5 × 10-3 m3 . If the work done in compressing the gas at constant pressure is 100 J. Find the final volume of the gas. |

Answer» Data : P = 1 × 105 N/m2 , V = 5 × 10-3 m3 , W= -100 J W = P(Vf – Vi) ∴ Vf – Vi = \(\frac{W}{P}\) ∴ Vf = Vi + \(\frac{W}{P}\) = 5 x 10-3 + \(\frac{(-100)}{(1\times10^5)}\) = 5 × 10-3 -1 × 10-3 = 4 × 10-3 m3 This is the final volume of the gas. |
