Which of the following statement(s) is/are true? A. Hardness: It is the property of matter to allow volume reduction under high pressure and this property is shown by gases. B. Shape: It is the property of a substance that flows easily and allows it to change its shape under external force and this property is exhibited by both liquids and gases.

Which of the following statement(s) is/are true? A. Hardness: It is the property of matter to allow volume reduction under high pressure and this property is shown by gases. B. Shape: It is the property of a substance that flows easily and allows it to change its shape under external force and this property is exhibited by both liquids and gases. Correct Answer Both A and B are false.

The correct answer is Both A and B are false.

  • Both A and B are false.

Key Points

  • Hardness is a material's resistance to localized plastic deformation.
    • From ultra-hard materials like diamond and boron-carbide to various ceramics and hard metals, to soft metals, polymers, and soft tissues, hardness is measured.
    • Hardness is only one mechanical property to consider; other properties such as toughness and strength must also be taken into account, as hard materials have poor toughness and are readily fractured.
  • In contrast to other attributes such as colour, texture, or material type, a shape is an object's external boundary, contour, or external surface.
    • The volume and shape of a solid are both defined.
    • Although a liquid has a defined volume, it lacks a defined shape.
    • Gas doesn't have a defined volume or shape.

Important Points

  • Fluidity is the property of a substance to easily flow and allow a change in its shape under external forces and this property is exhibited by both liquids and gases.
  • Compressibility is the property of matter to allow compression under high pressure and the gases show this property.

Which of the following statement(s) is/are true? A: Compressibility: The property of matter due to which its shape does not change after applying external force. Solids show this property. B: Fluidity: It is a property of matter to flow easily and change shape under external force. This property is exhibited by both liquid and gas.
Which of the following statements is/are true? A. Rigidity: According to the type of matter, shape differs, depending upon location of particles. Eg, solids have definite shape while liquids acquire the shape of their container and gases, as such. don’t have any shape. B. Compressibility: It is the property of matter to allow a decrease in volume under high pressure and gases show this property.
Which of the following statement is true? A. Firmness: According to the type of matter, the size of a substance depends on the position of its particles. For example, solids have a fixed shape while liquids acquire their vessel shape and gases have no shape. B. Size: This is the property of a substance in which its volume decreases under high pressure. This property is found in gases.
Which of the following statement(s) is/are true? A. Shape: According to the type of matter, the shape changes depending on the location of the particles. For example, solids have a definite shape, whereas liquids acquire the shape of their vessel and, seen, gases have no shape. B. Filling a vessel of water: It is a property of matter, which decreases in volume under high pressure, and gas shows this property.
