Which of the following statement(s) is/are true? A. Hardness: It is matter’s property that allows 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

1. Both A and B are false.
2. Only A is true.
3. Only B is true.
4. Both A and B are true.

The Correct statements is A. Hardness: It is matter’s property that allows volume reduction under high pressure, and this property is shown by gases and 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 are false.

• A material’s resistance to localized plastic deformation is measured by its hardness.
• Hardness is assessed for anything from soft metals, polymers, and soft tissues through soft tissues, soft metals, hard metals, and ultra-hard materials like diamond and boron-carbide.
• Hard materials have weak toughness and are easily fragmented. Thus other mechanical properties like toughness and strength must also be considered. Hardness is merely one such mechanical property to take into account.
• A form is an object’s external boundary, contour, or external surface, as opposed to other qualities like color, texture, or material type.
• A solid has a defined shape as well as volume.
• A liquid lacks a distinct shape but has a defined volume.
• There is no established volume or shape for gas.
• Both liquids and gases exhibit the quality of fluidity, which is the ability of a substance to flow readily and permit a change in its shape in response to external influences.
• The ability of a substance to be compressed under high pressure is known as compressibility, and gases exhibit this ability.
