  3. Why did the water level in the kettle reduce?
  4. Define condensation in your own words.

Answers:

  1. 100°C
  2. Condensation
  3. Because water was changing into vapour and escaping
  4. Condensation is the process where water vapour turns back into liquid form

📝 Case Study Question 3

Read the passage and answer the following questions:

During a school trip, students visited a hill station where they noticed fog in the morning and frost on leaves. The guide explained that temperature plays a key role in changing the form of water in nature. The teacher asked the students to connect these observations with scientific terms.

Answer the following:

  1. What process leads to the formation of fog?
  2. How is frost formed?
  3. What role does temperature play in these changes?
  4. Name the state of water in fog and frost.

Answers:

  1. Condensation of water vapour
  2. Freezing of water vapour on cold surfaces
  3. Temperature drop causes gas to turn into liquid or solid
  4. Fog: Liquid (tiny droplets); Frost: Solid
