Properties of Matter
![Page 2: Properties of Matter. To identify a chemical change look for observable signs such as: Color change Bubbling and fizzing Light production Smoke Presence.](https://reader033.fdocuments.in/reader033/viewer/2022042822/5697c0141a28abf838ccd90a/html5/thumbnails/2.jpg)
To identify a chemical change look for observable signs such as:
• Color change
• Bubbling and fizzing
• Light production
• Smoke
• Presence of heat or cold
• Formation of precipitate

Phase Changes
Exo-releases heat to environment
Endo-absorbs heat from environment

An extensive property of a material depends upon how much matter is is being considered.
An intensive property of a material does not depend upon how much matter is is being considered.
• mass
• length
• volume
• density
• temperature
• color
Extensive and Intensive Properties

DensityDensity
• Density is a property that describes the relationship between mass and volume
• Density can be found by dividing mass by volume

Density of FluidsDensity of Fluids• A fluid is defined as any matter that has the ability
to flow
• You can find the density of a fluid by measuring both mass and volume and then plug it into the density equation
• Most liquids are less dense than the solid form because the particles in a solid have a fixed arrangement and do not have the ability to flow.

What is What is Viscosity?Viscosity?
•A measure of a material’s A measure of a material’s resistance to flowresistance to flow
Which substance here has a higher viscosity?

Effect of heat on viscosity Effect of heat on viscosity • Increased heat will reduce the
viscosity of a fluid and thus the fluid friction.
• A good example is how warm ketchup flows quicker than cold .
• Some people describe viscosity as thickness or sluggishness.

Changing surface Changing surface characteristics characteristics
• You can reduce the friction of a fluid sliding along a surface by improving the surface characteristics or texture of the solid object.
• A rough surface texture will provide more resistance than a smooth surface in most cases. Even if the surface is smooth, having protrusions such as rivets and screw heads can increase the friction.
