5. Why does a wet hand feel cooler when air is blown over it?

6. Why do water droplets appear on the outside of a cold glass?

7. Why is water in an earthen pot often cooler?

8. What is the water cycle?

Section F: Think and Apply

1. If you want your clothes to dry quickly on a sunny day, what steps can you take?

2. Why does a fan help wet clothes dry even though the fan does not produce heat?

3. A cold bottle is taken outside on a humid day. After some time, water droplets appear on its outer surface. Explain why.

4. Why does a puddle disappear faster on a hot, windy day than on a cool, still day?

5. Why should we avoid wasting clean water?

Section G: Complete the Water Cycle

Fill the missing words:

Water from oceans, lakes and rivers is heated by the Sun and changes into water vapour. This process is called .

As moist air cools, water vapour changes into tiny droplets. This process is called .

Water then falls from clouds to Earth’s surface. This is called .

Water collects in rivers, lakes, groundwater and oceans and the cycle continues.

Section H: Observe and Explain

Activity: Wet Hand and Dry Hand

Wet one hand with water and leave the other hand dry. Blow air across both hands.

1. Which hand feels cooler?

2. Why does it feel cooler?

3. What role does evaporation play?

Write whether each change will generally make evaporation faster or slower.

Situation	Faster or Slower?
Water spread over a large plate	________________
Water kept in a small deep container	________________
Wet clothes kept under moving air	________________
Water kept in a warm place	________________
Water kept in very humid air	________________

2. Why can a wet floor feel cooler after water is sprinkled on it?

3. A student says, “Water droplets outside a cold glass come from the water inside the glass.” Do you agree? Explain.

4. Why may clothes take longer to dry on a humid day?
