    The terms in column X are somehow related to the terms in columns Y and Z. Match the columns correctly.
    X Y Z
    1.       Planck Nuclear constant Mass wave
    2.       Raoult Angstrom Threshold energy
    3.       De Broglie Moderator Heavy water
    4.       Einstein Erg-second Molecular weight
    5.       Nuclear reactor Vapour pressure lowering \[E=m{{c}^{2}}\]
    6.       Mass defect Photoelectric effect \[6.626\times {{10}^{-27}}\]

    Answer:

                    The correct matching in tabular form is given below :
    X Y Z
    1.       Planck 1.       Erg-second 1.       \[6.626\times {{10}^{-27}}\]
    2.       Raoult 2.       Vapour pressure lowering 2.       Molecular weight
    1.       De Broglie 3.       Angstrom 3.       Mass wave
    3.       Einstein 4.       Photoelectric effect 4.       Threshold energy
    4.       Nuclear reactor 5.       Moderator 5.       Heavy water
    5.       Mass defect 6.       Nuclear constant 6.       \[E=m{{c}^{2}}\]
