Definitions
A measure of the speed at which a fluid flows from one point to another.
What is flow rate?
Between cooking oil, corn syrup, and coca-cola, which substance has the highest viscosity?
What is corn syrup?
How do you calculate volume?
What is length x width x height?
True or False: All fluids are liquids.
What is a false? Fluids can also be gasses or a solid that has been given the properties of a fluid (eg. air in sand)
The upward force that all fluids exert on objects. If something rises or sinks in a fluid.
What is buoyancy?
A fluid that is very resistance to flowing has a high _________.
What is viscosity?
The type of matter in which particles are moving very slowly.
What is a solid?
Name 3 fluids that are important for life.
What are water, blood, urine, saliva, sweat, stomach acid?
Between ice and water, the substance that has a higher density and how we know this.
What is water has a higher density? We know this because ice floats on water.
Increasing the temperature of a fluid will usually result in a(n) _______________ in its flow rate.
What is increase?
The amount of matter in an object.
What is mass?
True or false: The human circulatory system is hydraulic.
What is true? A hydraulic system using liquids under pressure. Our circulatory system is pumped by our heart (exerting pressure) and blood is the liquid.
Using a gas, usually air, under pressure to transmit a force.
What is Pneumatic System?
The density of an object that has a volume of 10 ml and a mass of 20 grams.
What is 2g/ml?
Three factors that we learned about that can affect the flow rate of a fluid.
What are the size of the fluid's particles, the pressure exerted on the fluid, the temperature of the fluid, the diameter of the tube that a fluid flows through?
Using the term 'particles', explain why two objects with the same volume may have different densities.
What is, that the more dense object has particles that are packed more tightly together, OR it has more particles than the other object?
What is thermal expansion?
A _________ flows, spreads out evenly when poured, and exerts pressure.
What is a FLUID?
Between a solid, liquid, or gas, the substance that has the weakest attraction between particles.
What is a gas?
What is displacement?
The density of pure water.
What is 1 g/mL?
A hairspray cannister will explode if heated. Why?
What is particle expansion? The particles of the gas must become further apart as it is heated, putting pressure on the cannister and eventually causing it to explode.
