A gas cylinder is filled with gas occupies 150cc at 200C and 800mm of Hg pressure. What will be its volume at 270C and 300mm of Hg pressure? |
| Answer» VOLUME of the gas = 0.43 LExplanation:Volume of the gas (V₁) = 150 ccTemperature of the gas (T₂) = 200° CPressure (P₁) = 800 mm of HgTemperature (T₂) = 270° CPressure (P₂) = 300 mm of HgVolume of the gas (V₂)➠ First we have to covert all the given datas to the respective S.I units.➠ Pressure: 800 mm of HG = 1 ATM 300 mm of Hg = 0.4 atm➠ Temperature: 200° C = 473.15 K 270° C = 543.15 K➠ Volume: 150 cc = 0.15 L➠ Now by the Ideal gas equation we know that, ➠ Substitute the data, ➠ Simplifying, 3.17 × 10⁻⁴ = 7.36 × 10⁻⁴ × V₂ V₂ = 3.17/7.36 V₂ = 0.43 L➠ Hence the gas occupies a volume of 0.43 L. | |
