Rainbow 🌈 mind map and MCQ of Liquid pressure

Rainbow 🌈 mind map Liquid Pressure

Direction:  Liquids exerts pressure in all directions. 

Pascal's Law: The pressure exerted by a Liquid at a depth is same in all directions.

Buoyant force: Due to difference in pressure at bottom and top of an object immersed in a liquid, a force acts on a body in upward direction called Buoyant force. 

Factors affecting:

   1. The height of liquid column 

   2. The density of a liquid                         

Affect of liquid column: liquid pressure at a point increases with increase in height of a liquid column. 

Affect of density of a liquid 

• Liquid pressure increases with increase in density of a liquid.   

Hydrostatic Paradox: A liquid seeks its own level.

Rainbow 🌈 MCQ of Atmospheric Pressure 

 

1.Liquid exerts pressure 

 A) in upward direction only
 B) at bottom only
 C) in all directions 
 D) None of these

ANSWER= (C) at bottom only. 
Explain:- Liquid exerts pressure in all directions .

 

2. The pressure exerted by a Liquid at a any depth is same in all directions. -

 A) Liquid pressure 
 B) Hydrostatic Paradox 
 C) Pascal's law
 D) none of above. 

ANSWER= (C) Pascal's law .
Explain:- Pascal's Law states that- The pressure exerted by a Liquid at a any depth is same in all directions  

 

3. When an object immersed in a liquid, it experiences upward force called 

 A) buoyant force 
 B) static force 
 C) force of gravity 
 D) all of above 

ANSWER= (A) buoyant force 
Explain:- When an object immersed in a liquid, it experiences upward force called Buoyant force. 

 

4. Factors affecting liquid pressure-

 A) height of a liquid column 
 B) density of a liquid 
 C) both
 D) none of above 

ANSWER= (D) both
Explain:- Factors affecting a liquid pressure are height of a liquid column and density of a liquid. 

 

5. When height of a liquid column increases, liquid pressure 

 A) remains the same 
 B) decreases 
 C) increases 
 D) not affected  

ANSWER= (C) increases 
Explain:-  When height of a liquid column increases, liquid pressure increases. 

 

6.More the liquid density, _____ pressure exerted by it.

 A) zero
 B) less
 C) more
 D) None of above

ANSWER= (C) more
Explain: when density of a liquid increases, liquid pressure increases.

 

7. The height of level of a liquid in tubes of different area of a cross section ______, although volume of liquid is different in different tube.

 A) differs
 B) always remains same.
 C) sometime becomes same 
 D) none of above 

ANSWER= (B) always remains the same.
Explain:- A liquid seeks its own level.
