Most Important & Most Repeated MCQs

  • NaCl (Solid)
  • NaCl (Molten)
  • NaCl (Aqueous)
  • Both B & C
  • a
  • In NaCl, Ions are fixed in place or in solid form and cannot move.
    In NaCl (Molten / Melted), Ions are free to move and electricity can flow.
    NaCl (Aqueous / dissolved in water), Na and Cl can dissolved in water and can carry current.

  • 25 C and 2 atm
  • 0 K and 1 atm
  • 25 K and 0.5 atm
  • 0 C and 1 atm
  • d
  • 1ATM (atmosphere) is a normal air pressure at sea level.
    1ATM is equal to 760 Torr.
    In simple words atm is unit of Pressure.
    The space (volume) that 1 mole of a gas takes is called molar volume.

  • Temperature
  • Intermolecular forces
  • Atmospheric pressure
  • Molecular mass
  • a
  • Viscosity is the resistance of liquid to flow.

  • Temperature
  • Work done
  • Internal energy
  • Pressure
  • b
  • Temperature, Internal Energy and Pressure are state functions.

  • 4.184 joule
  • 41.48 joule
  • 418.4 joule
  • 4184.0 joule
  • a
  • 1 Kilocalorie is equal to 4184 J.
    A calorie is the amount of heat required to raise the temperature of 1 gram of water by 1°C.

  • Reduction occur cathode
  • Oxidation occur at cathode
  • Electron flow from cathode to anode
  • Both A and B
  • a
  • Oxidation occurs at anode.
    Electron flow from anode to cathode.
