mass
It refers to the amount of matter present in a sample.
Matter
Anything that has mass and occupies space.
Various forms of energy such as heat, light, and electricity
What are the things that not considered to be matter?
Solid Liquid Gas
Matter exists in three physical states:
• Volume and Shape
• Density
• Compressibility
• Thermal Expansion
WHAT ARE THE COMMON PHYSICAL PROPERTIES OF MATTER
Compressibility
It is a measure of the change in volume of a sample of matter resulting from a pressure change.
Thermal Expansion
It is a measure of the change in volume of a sample of matter resulting from a temperature change.
Solid
The physical state characterized by a dominance of potential energy (cohesive forces) over kinetic energy (disruptive forces).
Liquid
A physical state that the particles that are randomly packed but relatively near one another.
Gas
The physical state characterized by a complete dominance of kinetic energy (disruptive forces) over potential energy (cohesive forces).
Liquid
The physical state characterized by potential energy (cohesive forces) and kinetic energy (disruptive forces) of about the same magnitude.
Solid
A physical state that each particle occupies a fixed position, about which it vibrates because of disruptive kinetic energy.
Gas
A physical state that attractive forces among particles are very weak and are considered to be zero.
Liquid
A physical state that the molecules are in constant, random motion; they slide freely over one another but do
Gas
A physical state that the particles move essentially independently of one another in a totally random manner.
Liquid
A physical state that has:
• DEFINITE VOLUME AND INDEFINITE SHAPE
• HIGH DENSITY
• SMALL COMPRESSIBILITY
• SMALL THERMAL EXPANSION
Solid
A physical state that:
• DEFINITE VOLUME AND DEFINITE SHAPE
• HIGH DENSITY
• SMALL COMPRESSIBILITY
• VERY SMALL THERMAL EXPANSION
Gas
A physical state that:
• INDEFINITE VOLUME AND INDEFINITE SHAPE
• LOW DENSITY
• LARGE COMPRESSIBILITY
• MODERATE THERMAL EXPANSION
