Question 1

3 Factors affecting liquid pressure

Answer 1

Gravitational acceleration
Density of liquid
Depth of liquid

Question 2

3 Characteristics of liquid pressure

Answer 2

Acts in all direction
Same point, same pressure
Not affected by shape and cross section of container

Question 3

Definition of Atmospheric Pressure

Answer 3

Pressure due to weight of layer of air acting on surface of the earth

Question 4

Apparatus to measure
1) Gas Pressure
2) Atmospheric Pressure

Answer 4

1. Manometer
2. Barometer

Question 5

Pascal’s Principle

Answer 5

Pressure is uniformly transmitted in an enclosed fluid in all directions

Question 6

Archimedes’ Principle

Answer 6

Object fully or partially immersed in fluid experience buoyant force equal to weight of fluid displaced

Question 7

Definition of buoyant force

Answer 7

Force acting upward on an object immersed in liquid when there is pressure difference between lower surface and upper surface of object

Question 8

Bernoulli’s Principle

Answer 8

When velocity of fluid increase, pressure of fluid decreased and vice versa
