3. Figure shows two cylinders connected with a common light piston as shown in figure. Cylinder wallsand piston are thermally insulated. Cross-sectional area of cylinders are A and 2A and they containdifferent gases H
2 and O
2 respectively. Pistons are open to atmosphere at one end as shown in figure.
Lycopodium powder is sprinkled on the lateral surface of the two cylinders. Pistons can be set intolongitudinal vibrations such that longitudinal standing wave can be set in the cylinders due to whichpowder at the base of cylinder gets collected at the certain positions. The length of gas columns is suchthat both the air columns resonate with the external driver frequency. Initially both the gasses are at sametemperature and H
2 chamber oscillates in first overtone and O
2 chamber in third overtone. Mark correct
statements (Take P0 = 105 N/m2, A = 10–4 m2) :-
(A) After standing wave is set, if the separation between consecutive heaps of powder collected in H2
chamber is 7 cm, then the separation in O2 chamber is
74
cm
(B) Now H2 chamber is supplied heat such that gas expands and piston shifts by 1 cm work done by
atmosphere as piston shifts is 0.2 J(C) Process in O
2 chamber is isothermal
(D) Process in O2 chamber is adiabatic

Paragraph for Questions 9 and 10Even if surface tension is most important only for liquids, we shall here consider a simple regular "solid"surrounded by vacuum. The molecules are placed in a cubic grid (see the figure given below) with gridlength equal to the molecular separation length L
mol. Each molecule in the interior has six bonds to its
neighbors whereas a surface molecule has only five. If the total binding energy of a molecule in the bulk
is Î, a surface molecule will only be bound by 5
6Î. The missing binding energy corresponds to adding
an extra positive energy 1
6Î for each surface molecule.
The binding energy may be estimated as Î » hm where h is the latent heat of evaporation and
3molmol
A
Mm L
N= = r is the mass of a single molecule. Dividing the molecular surface energy
1
6Î with the
molecular area scale 2molL , we arrive the following estimate of the surface energy density..
2 2
11 166 6 mol
mol mol
hmh L
L L
Îa » » » r
The appearance of the molecular separation scale is quite understandable because rLmol
represents theeffective surface mass density of layer of thickness L
mol. One might expect that the smallness of the
molecular scale would make the surface energy density insignificant in practice, but the small thicknessis offset by the fairly large values of r and h in normal liquids, for example water.Consider 3 liquids(P) h = 105 J/kg, r = 104 kg/m3, L
mol = 10–7 m
(Q) h = 4 × 105 J/kg, r = 103 kg/m3, Lmol
= 3 × 10–7 m

Paragraph for Questions 11 and 12iz'u 11 ,oa 12 ds fy;s vuqPNsn
Energy is often releases or absorbed in a nuclear reaction. A reaction releases energy when kineticenergy of product nuclei after reaction is greater than the kinetic energy of interacting nuclei beforereaction, the increase results from the transformation of rest mass into kinetic energy. The Q value ofnuclear reaction (amount of energy released)Q Value = SE
kf – SE
ki
SEkf = final kinetic energy
SEki = initial kinetic energy
Q Value = SBi – SB
f
SBi = initial binding energy
SBf = final binding energy
For an exoergic reaction Q > 0, such reaction can proceed even the reacting particles are at rest. Forendoergic reaction Q < 0, such reaction requires threshold kinetic energy. The nuclear reaction followscertain conservation of(i) charge (ii) linear and angular momentum (iii) mass and energy.ukfHkdh; vfHkfØ;k esa ÅtkZ lkekU;r;k vo'kksf"kr ;k mRlftZr gksrh gSA ;fn vfHkfØ;k ds ckn mRikn ukfHkdksa dh xfrtÅtkZ dk eku] vfHkfØ;k ls iwoZ fØ;kdkjd ukfHkdksa dh xfrt ÅtkZ ls vf/kd gks rks Å"ek mRlftZr gksrh gS rFkk ;gvfrfjDr ÅtkZ fojke æO;eku ds xfrt ÅtkZ esa :ikUrj.k ds QyLo:i izkIr gksrh gSA ukfHkdh; vfHkfØ;k dk Q eku(mRlftZr ÅtkZ dh ek=k) fuEu izdkj fy[kk tkrk gSAQ eku = SE

Paragraph for Questions 11 and 12

Molecular orbital theory is based on linear combination of atomic orbitals (LCAO). According to LCAO
when respective atomic orbitals of the atoms interact, they undergoes constructive and destructive
interference giving two types of molecular orbital i.e. bonding and antibonding molecular orbitals
respectively.
