Pressure in Liquid

Open Ended

If you are a scientist, what do you think caused the Nanggala submarine to disappear?

​Factors affecting the pressure in a liquid

There are 4 properties of pressure​...

Open Ended

Based on the picture, can you guess, what is the 1st properties of density in liquid?

(HINT : blue arrows are pressure)

Open Ended

So, how about this one. What is the 2nd properties of pressure in liquid?

(HINT : the place where you are influence the pressure )

​2. The greater the gravity, the greater the pressure

​The pressure of the liquid that will be given is different, depending on the magnitude of gravity at your place.

If the object dive on the earth and on the moon, surely the pressure given will be different

And then how about the 3rd properties, based on the picture?

(HINT : relation between pressure and depth)

Open Ended

In your opinion, why we can't dive too deep?

YEAYYY.. the last one.

What is the 4th propertis of pressire in liquid?

(HINT : kind of liquid, dense and less dense)

Open Ended

So, from the properties of the liquid that we have discussed, can you tell me, what is the formula of pressure in liquid?

(HINT : properties that affect pressure in liquid)

Example ​

If an object of 1 kg is placed in water having a density of 1000 kg/m^3 at a depth of 30 cm. So what is the hydrostatic pressure that occurs? ( g = 10 m/s^2)​
