Density and pressure

How to calculate density

mass / volume

explain how you would measure the density of a irregular shape

use eureka can that is filled with water, place the object with a tube that is going to be filled up with water. That will give you. the volume, weigh the object and then calculate the dnesity using the formula mass/ volume.

What is the formula for pressure

force /area

explain if a smaller area or a larger area will exert more force?

When there is a more smaller area, that means there will be a greater amount of force since it focuses on one little point to add the pressure in.

How to calculate pressure difference

Height x density x gravitational field strength
