    A cylinder with a movable piston contains 3 moles of hydrogen at standard temperature and pressure. The walls of the cylinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume?

    Question

    A cylinder with a movable piston contains 3 moles of hydrogen at standard temperature and pressure. The walls of the cylinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume?

    The cylinder is completely insulated from its surroundings. As a result, no heat is exchanged between the system (cylinder) and its surroundings. Thus, the process is adiabatic.

    Initial pressure inside the cylinder =P

    1 ​

    Final pressure inside the cylinder =P

    2 ​

    Initial volume inside the cylinder =V

    1 ​

    Final volume inside the cylinder =V

    Ratio of specific heats, γ=

    C V ​ C P ​ ​ =1.4

    For an adiabatic process, we have:

    P 1 ​ V 1 γ ​ =P 2 ​ V 2 γ ​

    The final volume is compressed to half of its initial volume.

    ∴V 2 ​ =V 1 ​ /2 P 1 ​ V 1 γ ​ =P 2 ​ (V 1 ​ /2) γ P 2 ​ /P 1 ​ =V 1 γ ​ /(V 1 ​ /2) γ =2 1.4 =2.639

    Hence, the pressure increases by a factor of 2.639.

    Two moles of an ideal gas is contained in a cylinder fitted with a frictionless movable piston, exposed to the atmosphere, at an initial temperature T(0). The gas is slowly heated so that its volume becomes four times the initial value. The work done by gas is

    d. Since the gas is slowly heated, it remains in equilibrium (more or less) with the atmosphere, i.e., the process takes place at a constant pressure. Now, from PV = nRT, PdV = nRdT or, P Delta V = nR Delta T But P Delta V is the work done by the gas. So, Delta W = nR Delta T = (2 mol) (R ) (4 T(0) - T(0)) = 6 RT(0) [From Eq. (i) Delta V prop Delta T, i.e., if Delta V = 3V(0), Delta T = 3 T(0)]

    The correct Answer is D

    Solution

    d. Since the gas is slowly heated, it remains in equilibrium (more or less) with the atmosphere, i.e., the process takes place at a constant pressure.

    Now, from PV=nRT,PdV=nRdT PV=nRT,PdV=nRdT or, PΔV=nRΔT PΔV=nRΔT But PΔV PΔV

    is the work done by the gas.

    So, ΔW=nRΔT=(2mol)(R)(4 T 0 − T 0 )=6R T 0

    ΔW=nRΔT=(2mol)(R)(4T0-T0)=6RT0

    [From Eq. (i) ΔV∝ΔT ΔV∝ΔT , i.e., if ΔV=3 V 0 ,ΔT=3 T 0 ΔV=3V0,ΔT=3T0 ] Class 12 Class 11 Class 10 Class 9 Class 8 Class 7 Class 6
