Brick has a mass of 6,000g and a volume of 2,000cm^3.
What is 3.00g/cm^3?
You have a slice of pizza. You take a few bites of the slice of pizza. Did the density of the pizza change?
No! The mass changed because you ate it, and the volume changed because you ate it, but that keeps the density the same.
weight of object is also known as
gravitational force.
measures the amount of gravitational force acting on an object
What is weight?
A floating object is put into a liquid, and you watch the water level rise because of this. This rise in water level is known as_________ in Archimedes formula?
What is displaced water?
A metal has a volume of 15cm^3 and density of 3.0g/cm^3. It's mass would be....
What is 45 g?
What is the density of pure water?
1.0 g/mL
the weight of a displaced liquid is also known as
the buoyant force.
The tool used to measure liquid volume.
What is a graduated cylinder?
the buoyant force on an object in a liquid is 100 N. What is the weight of the volume of water it displaced?
also 100 N.
A shoe box has a volume of 500.00cm^3 and mass of 750.0 grams. Its density is...
What is 1.5 g/cm^3?
How does a decrease in volume of an object affect the density of the object?
Density is how tightly packed atoms in a substance are. If you make the substance smaller, but don't change the amount of atoms, the atoms will be tightly packed.
Does a floating object have [balanced/unbalanced] forces?
balanced
an object sinks when it displaces a volume of water that has a weight _______ the object's weight
less than the object's weight.
A liquid has a mass of 24g and density of 2.0g/mL. It's volume is this....
What is 12 mL?
Item has a density of 2.5g/cm^3. Will it sink or float in water?
sink!
Density units
What is g/mL or g/cm^3
An object sinking with a changing speed has a [balanced/unbalanced] force?
unbalanced force
The amount of matter in a given volume
What is density?
What is the gravitational force on a suspended object that displaces 60 N of water?
60 N
A liquid has a mass of 60g and volume of 30mL, its density is....
What is 2.0g/mL?
A pencil is floating in liquid A. Another pencil (of the same volume and mass) has sunk in liquid B. Use the terms density to make a comparison between liquid B and A.
Liquid B must be less dense than liquid A.
Which object has a greater buoyant force? A feather floating on the surface of a beaker OR a 50NT coin that has sunk in the beaker.
the 50 NT coin because it displaced more water by being fully submerged in the beaker.
