CHE 021 - LESSON 1 Flashcards
It is anything that has mass and takes up space (volume).
Made up of small particles, known as atoms.
Matter can be presented in different states, each of them has specific characteristics.
MATTER
These are characteristics of a substance which can be observed without changing its composition.
PHYSICAL PROPERTIES
How the substance looks and feels.
TEXTURE
How the object absorbs and reflects light.
COLOR
A measure of the average kinetic energy (energy of motion) of particles in a substance.
TEMPERATURE
The amount of space an object occupies in mL, L, cm3, m3, etc.
VOLUME
The ratio of mass to volume; reflects the degree of packing of particles in matter.
DENSITY
The way that a substance reflects light (metallic, non-metallic, glassy, pearly, dull).
LUSTER
Ability of a substance to be hammered flat and to retain the new shape.
MALLEABILITY
Ability of a substance to be stretched into a wire.
DUCTILITY
The exact temperature at which a solid becomes a liquid or a liquid becomes a solid
FREEZING TO MELTING POINT
One that DOES NOT depend on the amount of the substance present.
INTENSIVE PROPERTY
Depend only on the number of particles, not on their composition or internal arrangement.
EXTENSIVE PROPERTY
One that DOES depend on the amount of the substance present.
EXTENSIVE PROPERTY
Determined by the chemical composition of the particles and their structure (arrangement).
INTENSIVE PROPERTIES
