  • Question 1/5
    1 / -0.33
    Which of the characteristics of particles of matter is not true?
    Solutions

    Only the other three properties of particles of matter are correct. Particles of matter attract each other, they have space between them and they are continuously moving. But particles of matter do not repel each other. If it was so, then we could not have been able to see matter around us.

  • Question 2/5
    1 / -0.33
    Which of the following is not a property of a crystalline solid?
    Solutions
    In solids, constituent particles of matter are arranged in a specific manner which is called crystalline solids. These solids contain crystals in which these are having a definite geometry. There is a sharp freezing point in crystalline solids. This is because the distance between the same atoms or molecules or ions remains the same and constant.
  • Question 3/5
    1 / -0.33
    What is the nature of crystalline solid?
    Solutions

    The crystalline solids are anisotropic in nature, that is, some of their physical index show different values when measured along different directions in the same crystal.

    This arise from different direction in the same crystals. Hence, option B is correct.

  • Question 4/5
    1 / -0.33
    Which of the following is an amorphous solid?
    Solutions
    Quartz glass (SiO2) is an amorphous solid due to its short range order of constituent particles.
  • Question 5/5
    1 / -0.33
    Which among the following property is correct for amorphous solid?
    Solutions
    Isotropy generally refers to uniformity in all orientation. Amorphous solid is isotropic as the atoms and molecules do not have a repeating lattice pattern. Because of this random arrangement throughout, the values of physical property like refractive index, thermal conductivity etc possess same value in all direction. Their melting point is not definite as the bonds do not break all at once due to the indefinite lattice pattern.
