H. Case Study Based Questions

Case Study:
Riya kept ice cubes in a bowl on the table. After some time, the ice melted into water. Later, when the water was heated, it changed into steam. On a cold plate, she observed water droplets forming from the steam.

Answer the following questions:

  1. In which state was water at the beginning?
  2. What change occurred when the ice was kept at room temperature?
  3. What is the state of water after heating?
  4. Name the processes involved in these changes.
  5. What process caused water droplets to form on the cold plate?
  6. Explain why the particles move faster during heating.
  7. How does this case study demonstrate the three states of matter?

E. Short Answers:

  1. Matter is anything that occupies space and has mass. Examples: Water, Stone.
  2. Solids: definite shape and volume; Liquids: definite volume, no fixed shape; Gas: no definite shape or volume.
  3. Solids have a definite shape because particles are closely packed and cannot move freely.
  4. Liquids flow because particles are loosely packed and can move past each other. Examples: Water, Oil.
  5. Camphor, Dry ice
  6. Heating changes solids → liquids → gases; Cooling changes gases → liquids → solids. Examples: Ice melting, water boiling, dew formation.
  7. Gas particles move freely and spread out to fill available space.

F. Long Answers:

  1. Solids: definite shape and volume, closely packed particles. Liquids: definite volume, take shape of container, loosely packed particles. Gas: no definite shape or volume, far apart particles, compressible.
  2. Ice → water → steam → water droplets. Examples: Ice melting, water boiling, condensation.
  3. Gases are compressible because particles are far apart and can move closer.
  4. Solids: form structures; Liquids: for drinking, washing; Gases: breathing, inflating balloons.
  5. Melting (ice→water), Freezing (water→ice), Evaporation (water→vapor), Condensation (vapor→water), Sublimation (camphor→gas)
