Science Final Flashcards
The measure of how long matter is
Length
The amount of space an object takes up or occupies
Volume
Describes the amount matter in an object
Mass
A measurement of the gravitational force on an object
Weight
A measure of how hot or cold something is specifically, a measure of an average kinetic energy of the particles in an object
Temperature
The amount mass in a given volume
Density
anything that has mass and takes up space
Matter
A characteristic of a substance that can be observed without changing the identity of the substance. Examples; colors, shape, size, and texture
Physical properties
A change of matter form one form to another without a change in chemical properties
Physical change
- Flammability
2. Reactivity
Chemical properties
Occurs when one or more substances change into entirely new substances with different properties. Examples flammability, and relativity with substances such as oxygen, water, and acids
Chemical change
The smallest particle into which an element can be divided and still be the same element
Atom
CL (Chlorine) is an example of what
Molecule
H2O (water) is an example of what
Compound
Negatively charged particles that move within the electron cloud of an atom
Electrons
