Properties of matter quiz

Matter

anything that has mass and takes up space

property

a characteristic of a substance that can be observed

physical property

a characteristic that can be observed or measured without changing the identity of the substance

• malleability, solubility, melting point

melting point

the temperature at which a substance changes from a solid to a liquid at a given pressure

• water 0 degrees C

Boiling point

the point at which a substance changes from a liquid to a gas at a given pressure

• water 100 degrees C

Chemical property

pure substance

matter that has only 1 set of chemical and physical properties

• composed of only one type of molecule

• can be divided into compound and element

mixture

two or more pure substances mixed together. Each substance retains its own set of chemical and physical properties

• can be separated by physical means

Heterogeneous mixture

uneven distribution of substance- you can see the different parts

Homogeneous mixture

components are evenly mixed- cannot see the parts, it can still be separated by physical means

• salt water

compound

two or more elements chemically bonded together, cannot be separated physically-only separated by electrolysis

• carbon dioxide CO2

elements

substances made up of only one type of atom, cannot be separated by any physical or chemical process

• gold

particle
