P1.3.4 - Liquid Pressure Flashcards
1
Q
What is liquid pressure?
A
Pressure that is exerted by different liquids
2
Q
What happens to liquid pressure as you go deeper?
A
It increases
3
Q
How can you show that liquid pressure increases with depth?
A
Cut a hole in the bottom and top of a bottle, the water in the bottom will travel further horizontally as it is under more pressure
4
Q
Why does liquid pressure increase as you go deeper?
A
The molecules in any layer of the liquid are being compressed and pushed from above you
5
Q
What is the calculation for liquid pressure?
A
Pressure = column height * liquid density * gravitational field strength
6
Q
How can you calculate the difference between pressure at different depths?
A
Measure the pressure at both depths and find the difference
