Doctors Medicines MCQs Q&A

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.

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. Correct Answer Only A is true

The correct answer is Only A is true.

Key Points

  • Solid is the state in which matter maintains a fixed volume and shape.
    • The liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume, and gas is the state in which matter expands to occupy the volume and shape of its container.
    • So A is true.
  • Filling a vessel of water:
    • It is a property of matter, which decreases in volume under high pressure, and Liquid shows this property.
    • So B is False.​​​

Additional Information 

  • Matter can be classified as solid, liquid, and gas on the basis of interparticle forces and the arrangement of particles.
  • These three forms of matter are interconvertible by increasing or decreasing pressure and temperature. 
    • For example, ice can be converted from a solid to a liquid by increasing the temperature.
