Basics
Any substance that can flow and take the shape of the container that holds it.
Fluids
The basic unit of a chemical element.
Atom
This is one factor that can affect viscosity. _________ is the resistance that
a surface encounters when it rubs against another. ________ creates
resistance which slows the movement of liquids.
Friction
A state of matter that has no definite shape but has a definite volume.
Liquid
The center of an Atom, holds multiple charged subatomic particles. Name all three found inside the atom.
Proton, Neutron, Electron
_________ is a measure of how strongly fluid particles are attracted to each other. Fluids like honey or maple syrup have high ___________. This causes the fluid particles to stick together and flow slowly. Honey, maple syrup, and caramel are liquids that have a high viscosity.
Cohesion
A state of matter with no definite shape or volume.
Gas
A measure of the size of a body or region in three-dimensional space.
Volume
The attraction between the particles of a fluid and another substance. For example, honey makes contact with the jar that it is stored in. Fluid particles can attach to the sides of containers, causing the movement of the fluid to slow down. This also occurs in nature. Water at the centre of a stream tends to travel faster than water on the sides of the river.
Adhesion
A liquid's resistance to flowing (thickness).
Viscosity
A measure of the amount of matter in an object; a fundamental property of an object that is not affected by the forces that act on the object, such as the gravitational force.
Mass
_____ also influences a fluid's viscosity. An increase in _________will reduce a liquid’s viscosity, and a decrease in _________ will increase a fluid's viscosity. The opposite occurs when there is a _________change in gases.
Temperature
A theory used to explain the different properties and observations of solids, liquids and gases.
Particle Theory
"A special substance that doesn't act like most liquids we know. It doesn't flow the same way all the time. Instead, it can change how thick or thin it is when we press on it or move it around. "
Non- Newtonian
_______ affects viscosity based on the amount of a substance that is dissolved in a fluid. The higher the ________, the higher the viscosity.
Concentration
