Pa pascals
6
Q
How to increase pressure?
A
Increase temperature = increased kinetic energy
7

A
1000kg/m3
8
Q
When do objects float?
A
When the objects are lower density than water they float
9

Compactness
12
Q
How to measure density of regular object
A
Measure mass and volume and m/v = density
13
Q
Density unit
A
g/cm3 or kg/m3 x1000 to get to kg/m3
14
Q
How to measure density of irregular objects?
A
Water displaced from eureka can = volume of object
