Fluids
flow
What is more dense: pure gold or cork?
pure gold
What is viscosity?
Viscosity is a fluid's resistance to flow
weight is affected by gravity and mass is not.
What is the formula for finding mass
M=D x V
Which state of matter is NOT a fluid?
solid
What is the formula for finding density?
Density = Mass/Volume
What is a way to measure viscosity?
Flow rate
What is weight measured in?
Newtons
Which is NOT a unit for density? cm3, g/cm3, g/mL
cm3! This is a unit of volume
True or false: particles in gases are farther apart from each other than in solids
True
What is density?
Density is the mass of a substance per unit volume.
if something is more viscous than something else, is it thicker or thinner?
Thicker
What is the formula for finding the volume of a regular solid?
V= l x w x h
What is the volume of a cube with a side length of 5cm?
125cm3
Sand flows. Why isn't it considered a fluid?
Sand is a collection of individual smaller solids. So, it's actually not "flowing," and because it's a solid (fluids must be liquid or gas)
What is the density of water in g/mL?
1.0 g/mL
What is the method for finding the volume of an irregular solid?
water displacement
the mass of an object is 120g and its density is 30g/cm3. What is its volume?
4cm3
Ketchup is a special type of fluid called a what?
Non-Newtonian Fluid
An object has a density of 5.0g/mL. Will it sink or float in water?
It will sink
How would the particles behave in something with a fast flow rate?
They would have a weak force of attraction between them, allowing them to easily slide past one another
A container of water has 53mL of water in it. After adding a toy dinosaur, the water level rises to 97mL. What is the volume of the dinosaur?
44mL
A rock was placed in a graduated cylinder and the water level rose from 10mL to 35mL. The rock has a mass of 15g. What is its density?
0.6g/mL
