gas and liquid
state of matter that does not flow easily
solid

This transformation is technically interchangeable with _________
change
a reaction where no reaction actually occurs but only transformation
Physical Change
Physical change are seen through changes of:
Color
Texture
Temperature
Shape
Change of state: Boiling, melting, and evaporation
Physical change varies on the physical properties of a substance namely:
Density
Viscosity
Malleability
Luster
Property where the ____ of an object is its mass divided by its volume
density
The ____ of an object will also determine whether an object will sink/float
Density
The resistance to deformation of a particular chemical substance when a force is applied to it
Viscosity
One may think of viscosity in terms of ______
Thickness
Refers to as the quality of metals
Malleability
This means that the metals can deform under an amount of stress
Malleability
The property of an element that is defined based on the way it reacts with light
Luster
Occurs when there is a change in the composition
Chemical change
In chemical change, there is a ___ and ______
Reactant and Product
Signs of chemical reactions
Gas formation
Color Change
Noticeable odor
Formation of Precipitate

Atom
The concept of atomic theory was initiated by who?
John Dalton (1808)
What are the three parts of the atomic theory
