Pressure In Liquids Flashcards
1
Q
What’s liquid pressure?
A
The water molecules are pushing on each other and on surfaces and this liquid pressure acts in all directions
2
Q
What’s pressure and depth?
A
It’s like atmospheric pressure but the pressure at any point in a fluid depend on the weight of fluid above that point.
3
Q
Floating and sinking
A
Upthrust acts on any object that is floating or is submerged in a liquid. It is easy to work out why a rubber duck floats because of its weight. There are lots of water molecules hitting the bottom of the rubber duck than there are air molecules hitting the top.
