Fluid Flow
Of milk and honey, it is the substance that has a greater flow rate
What is milk
What is the definition of viscosity?
The thickness of a fluid
Name one real-life situation where we would use our knowledge of viscosity to help up do something.
Driving: selecting the right motor oil for our cars.
Cooking: melting chocolate.
Art: artists need to thin or thicken their paint.
What is the density of a liquid with a volume of 25mL and a mass of 100 g?
4 g/mL
What is the term for measuring fluid flow?
Flow rate
What is an example of a less viscous fluid?
Water, canola oil, milk, juice...
What is the definition of density?
A measure of mass per unit of volume.
Give an example of a fluid with a high density. (hint: think back to the experiment where we layered fluids on top of each other).
Syrup, Honey
What is the density of a liquid with a mass of 45 g and a volume of 320 mL?
0.14 g/mL
Do less viscous liquids have a greater flow rate?
Yes
What is an example of a more viscous fluid?
Honey, Syrup, BBQ sauce, Molasses...
What units can mass be measured in?
Kilogram, gram.
Water has a higher viscosity than maple syrup and flows faster.
False. Water does flow faster than maple syrup, but has a lower viscosity.
What is the volume of a liquid that has a density of 1.5 g/mL and a mass of 60 g?
40 mL
What is the definition of flow rate?
The measure of how quickly a fluid flows in a given amount of time
What is a way to increase the viscosity of a fluid?
Decreasing its temperature.
What is the density of a solid when compared to a liquid?`
More dense.
True or False. Water is more dense than oil.
True. That is why water sinks and oil floats on top.
What is the mass of a liquid with a density of 3.2 g/mL and a volume of 120 mL?
384 g
Do viscous liquids have a greater flow rate?
No
What measurement do we use to measure viscosity?
Flow rate.
You pour two liquids into a cup and notice that one liquid sinks below the other forming a layer. Based on this observation, you can say this about the top layer
What is that the top layer is less dense than the bottom layer.
What happens to the viscosity of a gas when it is heated?
It increases
If stacked on top of each other, which liquid would be the bottom layer: Liquid A with a volume of 130 mL and a density of 2.1 g/mL or Liquid B with a mass of 75 g and a volume of 30 mL?
Liquid B
