3. Distillation - Combination of two process separation

4. Ventilation- Circulation of air   

5. Condensation- Change of gas into liquid  


Subjective Type Questions

A. Answer the following questions in short


1. What are the three states of matter?

Answer: Three states of matter- Solids, Liquids and gases


2. Why are solid materials hard?

Answer: Solid materials are  hard because molecules in solids are tightly packed. 


3. How are the molecules in solids and liquids arranged differently?

Answer: Molecules in solids are tightly packed. 

Molecules in Liquids are loosely packed and are far apart. 

Molecules in gases are very loosely packed and are far apart. 


4. In what condition state of matter may change?

Answer: A matter may change from one state to another on heating or cooling. 


5. Give three examples of liquid-liquid solution.

Answer: Three examples of liquid-liquid solution-

i) lemon juice in water

ii) water in milk

iii) honey in milk 


 6. How is filtration different from evaporation?

Answer: Filtration- Separating Insoluble impurities from liquid through a filter paper. 

 Evaporation- Separating soluble impurities from liquid. 


B. Answer the following questions in detail


1. Mention any two properties for each of these - Solids, liquids, and gases. 

Answer: Two properties for each of these:

Solids: i) Solids have fixed shape and volume

            ii) Solids cannot flow

Liquids:  i)  liquids do not have fixed shape but have fixed Volume

              ii) liquids flow

 Gases: i) Gases  neither have fixed shape nor   fixed Volume

            ii) Gases flow


2. How does water change its state in three forms? Explain with the help of a drawing.

Answer: Water  exists in all three states, it changes from one state to another on heating or cooling.

 Ice changes to water on heating, water  changes to Vapour on heating.

Water vapour changes to water on cooling,  water changes to Ice on cooling.




3. What causes sea breeze?

Answer: During the day , the land gets heated by the sun much quicker than water in the seas, This causes the air to become lighter and rise creating a empty space just above the land. The colder and heavy air above the sea rushes towards the empty space created by the hot air above the land.  This phenomena causes a breeze to flow from see towards the land known as sea breeze. 


Picture-based Question
