2. Give the application of evaporation and vaporization

Competency

-process by which liquid changes to its vapours at a temperature below

its boiling point-takes place at all temperature. The

temperature may change during evaporation-is a slow and silent

process-takes place only at the

surface of the liquid-the rate of evaporation depend upon the surface

area of the liquid and the wind speed,

humidity and temperature

VAPORIZATION

- process by which liquid changes to its vapours at its boiling

point-takes only at a fixed temperature called boiling point of the

liquid. The temperature during vaporization

does not change-is a fast and violent

process-takes place over the

entire mass of the liquid-the rate of vaporization does not depend upon the surface area, wind speed, humidity and

temperature

EVAPORATION

INTRODUCTION

Additional Information

Evaporation can cause cooling.The particles of liquid absorb heat energy from the surrounding to regain the energy lost in the evaporation.

Vaporization undergoes the

process of evaporation and boiling.

ACTIVITYActivity 1

“Check Me”This activity tells the differences between

evaporation and vaporization.

Activity 2“Find Me”

This activity give some words related to the topic.

Activity 3“Where I am belong?”This activity tells the

applications of evaporation and vaporization.

Put a check (/) if you think it describes Evaporation or Vaporization

  Evaporation Vaporization

1 Quick process

2 Occurs at any temperature

3 Slow process

4 Takes places within liquid

5 Bubbles are formed

6 Heat supplied by surrounding

7 No bubbles are seen

8 Occurs at fixed temperature

9 Heat supply energy source

10 Temperature remains constant

11 Slow process

12 Temperature may change

Encircle if the phrase describes evaporation and

box the phrase if it describes vaporization.

Write true if the statement is correctAnd write false if the statement is wrong.

TRUE OR FALSE ENRICHMENT

__1. Sweat is an example of evaporation.__ 2. In vaporization, no bubbles can be see.__ 3. Vaporization undergoes evaporation and boiling..__ 4. Evaporation reached the boiling point.__ 5. Vaporization changed temperature.

__ 6. Vaporization’s temperature is hotter than Evaporation’s temperature.__ 7. Evaporation and Vaporization is the changed from liquid to gas.__ 8. We can see clearly evaporation occur than in vaporization.__ 9. Vaporization can harm you.__ 10. Smoke formed during vaporization.

ASSESSMENTFILL IN THE BLANK. CHOOSE THE WORD OF THE CORRECT ANSWER IN THE BOX.

Evaporation and Vaporization are the same in the change of phase of matter from 1_to gas. However, both has a big _2_. Evaporation happens in _3_ temperature while vaporization have a _4_ temperature. You can harm more in _5_ than in _6_. Vaporization is a _7_ and _8_ process while evaporation is a _9_ and _10_ process.

VOCABULARIESWind is the flow of gases on a large scale.

Humidity is the amount of water vapor in the air. A temperature is a numerical measure of hot or cold.

Liquid is one of the four fundamental states of matter, and is the only state with a definite volume but no fixed shape.Gas is one of the four fundamental states of matter. A pure gas may be made up of individual atoms, elemental molecules made from one type of atom, or compound molecules made from a variety of atoms.
