Examples
Give 2 examples of fluids
Water, Oil, Milk, Juice, etc.
Air, Helium, etc.
What are fluids?
A substance that can flow and spread out evenly when poured.
What is the process of liquid turning into solid called?
Freezing
What is viscosity?
The fluid's resistance to flow which is a result of friction between molecules.
What is the capital of Canada?
Ottawa
Give 3 examples of non-fluids
Wood, Rock, Metal, etc.
Which two states of matter are considered as fluids?
Liquids and gases
Which two states of matter have a fixed volume?
Solid and liquid
How do we measure viscosity?
Calculate the flow rate.
Flow rate = distance / time
What is the largest country in the world?
Russia
Give 2 examples of fluids that have low viscosity.
Water, Juice, Milk, etc.
True or False:
Very small solids (like flour) can flow, so they are considered as fluids.
False.
Solids that seem to flow form a heap, whereas fluids spread out evenly to fill whatever container they are in.
What is the process of solid turning into gas called?
Sublimation
What is the flow rate of a fluid if it takes 26 seconds to travel 52 centimeters?
2 cm/s
What animated movie is Baymax from?
Big Hero 6
Give 3 examples of fluids that have high viscosity.
Honey, Corn Syrup, Syrup, Molasses, etc.
Name one characteristic of a fluid.
- Can flow and move easily
- Can be compressed (gases) or have a fixed volume (liquids)
What are the four key ideas of the Particle Theory?
1. All matter is made up of tiny particles.
2. Particles are always moving.
3. Particles have spaces between them.
4. Particles attract each other.
How does temperature affect viscosity?
Heated: low viscosity, high flow rate
Cooled: high viscosity, low flow rate
What do you call a shape with 10 sides?
(Hint: pentagon, hexagon, octagon)
Decagon
Give 4 examples of different uses of fluids
Transportation, Cooling/Heating Systems, Industrial Machinery, Food and Beverage Industry, Medical Applications, Cleaning and Sanitation, Energy Generation, Agriculture, Environmental Uses, etc.
What is the difference between hydraulics and pneumatics?
Hydraulics use liquids, while pneumatics use gases.
What is the difference between vaporization and evaporation?
Vaporization happens when heat is applied. Evaporation can happen at room temperature.
Why is viscosity important?
- It affects how fluids behave
- Cooking (thickness of oils, sauces, syrups)
- Cosmetics (ease of application)
- Paints (adherence to surface)
- Lubricants (reduce friction)
