A certain volume of a gas at zero degrees Celsius and 1 atm pressure is 0.5 L. If the temperature is raised to 300 degrees Celsius by keeping the pressure constant, then what will be its final volume?
Correct answer: C. 1.05 L
- A. 1 L
- B. 0.1 L
- C. 1.05 L
- D. 1.50 L
Explanation
Using Charles's Law (V₁/T₁ = V₂/T₂), with temperatures in Kelvin. T₁ = 0°C = 273 K, and T₂ = 300°C = 573 K. V₂ = V₁(T₂/T₁) = 0.5 L × (573 K / 273 K) ≈ 1.05 L.

About Gases
Gas behaviour is explained through the kinetic molecular theory and the relationships among pressure, volume and temperature. Work includes STP, Boyle's and Charles's laws, absolute zero, the ideal gas equation, and the distinction between ideal and real gases, especially the effects of intermolecular forces and molecular volume.

Using van der Waals' equation, calculate the constant, a (atm Ltr2 mole -2) when two moles of a gas confined in a four litre flask exerts a pressure of 11 atm at a temperature of 300 K. The value of 'b' is 0.05 Litre mole-1.
The behaviour of a real gas is usually depicted by plotting the compressibility factor Z versus P at a constant temperature. At high temperatures and high pressure, Z is usually more than one. This fact can be explained by the van der Waals equation when:
Under identical conditions of temperature, the density of gas A is three times that of gas B, while the molecular mass of gas B is twice that of A. The ratio of pressures of A and B will be:
The Kinetic Molecular Theory of gases predicts pressure to rise as the temperature of a gas increases because :
A spherical air bubble is rising from the depth of a lake where the pressure is 'P' atm and the temperature is 'T' Kelvin. The percentage increase in its radius when it comes to the free surface of the lake will be. (Assume temperature and pressure at the surface are respectively P/4 and 2T Kelvin)
The system shown in the diagram is at equilibrium at 27oC and the volume of the bulb is 150 mL. At this temperature, the vapour pressure of water is 28 millimetres of mercury. If the bulb contains 0.001 mol of O2(g), the volume of the liquid water is approximately:
