Sample questions

1. Which state of matter has a definite shape and a definite volume?

   1. Solid
   2. Liquid
   3. Gas
   4. Plasma
   Show answer

   Answer: A. Solid

   Solids are characterized by their fixed shape and fixed volume due to the tightly packed arrangement of their particles with strong intermolecular forces.

2. Which state of matter can be compressed easily?

   1. Solid
   2. Liquid
   3. Gas
   4. Both liquid and gas
   Show answer

   Answer: C. Gas

   Gases are highly compressible because their particles are far apart, allowing them to be pushed closer together under pressure. Liquids and solids are much less compressible.

3. What happens to the particles of a substance when it is heated and changes from a liquid to a gas?

   1. They slow down and move closer.
   2. They speed up and move farther apart.
   3. They vibrate faster in fixed positions.
   4. They stop moving altogether.
   Show answer

   Answer: B. They speed up and move farther apart.

   When a liquid is heated to become a gas, its particles gain kinetic energy, move faster, and overcome the intermolecular forces holding them together, spreading out further.

4. Which property is NOT characteristic of a solid?

   1. Definite shape
   2. Definite volume
   3. Takes the shape of its container
   4. Particles vibrate in fixed positions
   Show answer

   Answer: C. Takes the shape of its container

   Solids have a definite shape. Liquids take the shape of their container.

5. What is the process of a solid turning into a gas without becoming a liquid called?

   1. Melting
   2. Vaporization
   3. Condensation
   4. Sublimation
   Show answer

   Answer: D. Sublimation

   Sublimation is the direct transition from the solid to the gaseous state. This bypasses the liquid phase.
