11.1 FLOATING AND SINKING Flashcards
What determines whether an object sink or float?
Density
What is the formula for density?
Density = mass/volume
What happens when the density is higher?
The object sinks
What happens when the density is lower?
The object floats
What is the density for water?
1.0g/cm^3
An object floats if the __________ is ____________ to the weight
upthrust; equal
Particles in liquid or gases collide with __________ objects
solid
Particles in ______ collide with floating object from above
air
Particles in _________ collide with floating object from below
water
The more force exerted on object depends on the difference between the forces due to the _____________________
particle size
Particles in dense liquid exert a _________ force because they are __________ (bigger/smaller)
bigger
Why is water less dense in solid state than it is in liquid state?
The solid structure of water molecules take up more space than while it is in liquid state
