Chp 1: Fluids
What is a fluid?
A substance that can flow and take the shape of its container.
What is flow rate?
the measurement of speed at which a fluid flows from one point to another
weight - a measure of how strongly gravity pulls on an object or substance
mass - a measure of the amount of matter in an object or substance
What's the full name of the high school that most students will end up attending?
G. L. Roberts Collegiate and Professional Institute
How long as Ms. Li been at Cannon for?
4 weeks
Describe the two types of flow and provide an example for each one.
Turbulent flow - chaotic changes in pressure and velocity
Laminar flow - smooth and regular, experiences little resistance
List the 4 fluids we worked with from lowest to highest expected viscosity.
water, corn syrup, honey, ketchup
If a the sides of a cube are each 2 cm then what is the volume (include units)? Remember the equation for volume is length x width x height.
2 cm x 2 cm x 2 cm = 8 cm3
How many compulsory courses do you need to take in grade 9 and what are they?
Six: English, Math, Science, Geography, French, Phys Ed
golden lab
What's an example of how the human body uses fluids to maintain a healthy lifestyle?
Optional responses:
- oxygen releases energy from food
- sweat cools the body down
- stomach acid aids the digestion of food
- blood acts as a transport
the thickness of a fluid, specifically the measure of how easily a fluid's particles can slide past one another
the amount of mass per unit of volume
What are the 2 optional subject areas that you can choose from?
The Arts
Business and Technology
What's Ms. Li's favourite colour?
yellow
gas, liquid, solid, and plasma
List at least 2 factors that affect flow rate.
pressure, type of surface the fluid is poured out of, size of the opening that the fluid is passing through, type of fluid, temperature, or method of transfer
If an object has a volume of 10 cm3 and a mass of 30g. What is the density (include units)? Remember that the equation for density is D = M/V.
D = M/V = 30 g/ 10 cm3 = 3 g/cm3
What is a component of education that is unique to G. L.?
What is Ms. Li's favourite book series?
The Hunger Games
What are the 5 points in the particle model according to the Particle Theory of Matter?
1) All matter is made up of tiny particles
2) Particles of matter are constantly moving
3) Particles have spaces between them
4) Adding heat to matter makes the particles move faster
5) Particles are attracted to one another
What is the difference between cohesion and adhesion?
Cohesion is the force of attraction between particles of a substance whereas adhesion is the attraction between 2 different kinds of particles.
If the bottle cap, in water, weighed 10 N. According to The Archimedes Principle, how much fluid would it displace?
10 N
4 classes, 75 minutes each
Which school does Ms. Li go to?
