Pressure is the force acting normally per surface area of an object.//
Force over surface area where direction of force is perpendicular to the surface area of an object.
The speed of air flow between two sheets of paper in Diagram 9.1 is lower than in Diagram 9.2
The distance between two sheets of paper, x in Diagram 9.1 is longer than in Diagram 9.2
When the speed of air between two sheets of paper increase,
the distance between two sheets of paper,x is decreases.
Bernoulli’s Principle
When the speed of air flow high , the pressure of air is low
Aerofoil
When the aeroplane moves the speed of air flows obove the wing is higher than below the wing
The air pressure above the wing is low while the pressure
Below the wing is higher.
Difference in pressure between above and below the wing causes the aeroplane moving up as the lifting force produce.

Discription
Large length/ size of pump
Small hole of at the end of pump nozzle
Small hole of at the end of bottle nozzle
Big size of bottle
Pump is made by strong material and light
Much more volume of air blows out
So that air blows out when its pumped is high velocity, and the air pressure is low
Rate of quantity of liquid out is small
It can filled with large quantity poison .
It can withstand the high pressure as the air in pump is
Compress.

Temperature is the degree of hotness
- The thermometer is put under the touge
- The heat is transferred from the body to the
thermometer
- Mercury expand until it reaches a state of
thermal equilibrium
- The temperature of the thermometer is the
same as the body
Aspect
Reasoning
Liquid used is Mercury
Expands uniformly // sensitive to changes in temperature
Thin glass walled bulb
More sensitive to heat
Small diameter of capillary tube
get a wider range // More sensitive to heat
Glass-bore stem and cross section - Thick and Curved
not easily to break // easy to read
C most suitable
